pp-GalNAc-T initiates the formation of mucin-type O-linked glycans; UDP-GalNAc: polypeptide alpha-N-acetylgalactosaminyltransferases (pp-GalNAc-T) initiate the formation of mucin-type, O-linked glycans by catalyzing the transfer of alpha-N-acetylgalactosamine (GalNAc) from UDP-GalNAc to hydroxyl groups of Ser or Thr residues of core proteins to form the Tn antigen (GalNAc-a-1-O-Ser/Thr). These enzymes are type II membrane proteins with a GT-A type catalytic domain and a lectin domain located on the lumen side of the Golgi apparatus. In human, there are 15 isozymes of pp-GalNAc-Ts, representing the largest of all glycosyltransferase families. Each isozyme has unique but partially redundant substrate specificity for glycosylation sites on acceptor proteins.

426-557 2.58e-70

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 16 (GALNT16) and similar proteins; GALNT16 (EC 2.4.1.41), also called polypeptide GalNAc transferase 16, GalNAc-T16, polypeptide GalNAc transferase-like protein 1, GalNAc-T-like protein 1, pp-GaNTase-like protein 1, polypeptide N-acetylgalactosaminyltransferase-like protein 1, protein-UDP acetylgalactosaminyltransferase-like protein 1, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 1, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT16 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 16 (GALNT16) and similar proteins; GALNT16 (EC 2.4.1.41), also called polypeptide GalNAc transferase 16, GalNAc-T16, polypeptide GalNAc transferase-like protein 1, GalNAc-T-like protein 1, pp-GaNTase-like protein 1, polypeptide N-acetylgalactosaminyltransferase-like protein 1, protein-UDP acetylgalactosaminyltransferase-like protein 1, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 1, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT16 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 14 (GALNT14)-like subfamily; The GALNT14-like subfamily includes GALNT14 and GALNT16. They act as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT14 displays activity toward mucin-derived peptide substrates such as Muc2, Muc5AC, Muc7, and Muc13 (-58). It may be involved in O-glycosylation in the kidney. Members of this subfamily comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 2 (GALNT2) and similar proteins; GALNT2 (EC 2.4.1.41), also called polypeptide GalNAc transferase 2, GalNAc-T2, pp-GaNTase 2, protein-UDP acetylgalactosaminyltransferase 2, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 2, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT2 has a broad spectrum of substrates for peptides such as EA2, Muc5AC, Muc1a, Muc1b. It is probably involved in O-linked glycosylation of the immunoglobulin A1 (IgA1) hinge region. It is also involved in O-linked glycosylation of APOC-III, ANGPTL3 and PLTP. It participates in the regulation of HDL-C metabolism. GALNT2 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

127-270 3.72e-14

Glycosyltransferase family A (GT-A) includes diverse families of glycosyl transferases with a common GT-A type structural fold; Glycosyltransferases (GTs) are enzymes that synthesize oligosaccharides, polysaccharides, and glycoconjugates by transferring the sugar moiety from an activated nucleotide-sugar donor to an acceptor molecule, which may be a growing oligosaccharide, a lipid, or a protein. Based on the stereochemistry of the donor and acceptor molecules, GTs are classified as either retaining or inverting enzymes. To date, all GT structures adopt one of two possible folds, termed GT-A fold and GT-B fold. This hierarchy includes diverse families of glycosyl transferases with a common GT-A type structural fold, which has two tightly associated beta/alpha/beta domains that tend to form a continuous central sheet of at least eight beta-strands. The majority of the proteins in this superfamily are Glycosyltransferase family 2 (GT-2) proteins. But it also includes families GT-43, GT-6, GT-8, GT13 and GT-7; which are evolutionarily related to GT-2 and share structure similarities.

441-554 5.50e-11

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 1 (GALNT1)-like subfamily; The GALNT1-like subfamily includes GALNT1 and GALNT13. They catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT1 has a broad spectrum of substrates for peptides such as EA2, Muc5AC, Muc1a, Muc1b and Muc7. GALNT13 has a much stronger activity than GALNT1 to transfer GalNAc to mucin peptides, such as Muc5Ac and Muc7. It can glycosylate SDC3. It may be responsible for the synthesis of Tn antigen in neuronal cells. Members of this subfamily comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

441-554 1.77e-10

ricin B-type lectin domain, beta-trefoil fold, found in Drosophila melanogaster polypeptide N-acetylgalactosaminyltransferase 9 (Pgant9) and similar proteins; The subfamily includes Pgant9 (also called pp-GaNTase 9, protein-UDP acetylgalactosaminyltransferase 9, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 9), Pgant4 (also called pp-GaNTase 4, N-acetylgalactosaminyltransferase 4, protein-UDP acetylgalactosaminyltransferase 4, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 4) and Pgant6 (also called pp-GaNTase 6, N-acetylgalactosaminyltransferase 6, protein-UDP acetylgalactosaminyltransferase 6, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 6). They function as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Pgant9 can both act as a peptide transferase that transfers GalNAc onto unmodified peptide substrates, and as a glycopeptide transferase that requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. Pgant4 and Pgant6 do not act as a peptide transferase, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. They prefer the diglycosylated Muc5AC-3/13 as a substrate. Pgant6 may have a role in protein O-glycosylation in the Golgi and thereby in establishing and/or maintaining a proper secretory apparatus structure. Members of this subfamily contain a ricin B-type lectin domain at the C-terminus. The ricin B-type lectin domain shows a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site.

441-552 1.51e-08

ricin B-type lectin domain, beta-trefoil fold; The ricin B-type lectin domain is a carbohydrate-binding domain formed from presumed gene triplication. It shows a beta-trefoil fold characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain was originally found in Ricin, which is a legume lectin from the seeds of the castor bean plant, Ricinus communis. It is also found in many carbohydrate-recognition proteins like plant and bacterial AB-toxins, glycosidases, or proteases, which serve diverse functions such as inhibitory toxicity, enzymatic activity, and signal transduction. The ricin B-type lectin domain can be present in one or more copies and has been shown in some instances to bind simple sugars, such as galactose or lactose. The most characteristic, though not completely conserved, sequence feature is the presence of a Q-W pattern. Consequently, the ricin B-type lectin domain has also been referred as the (QxW)3 domain and the three homologous regions as the QxW repeats. A disulfide bond is also conserved in some QxW repeats.

ricin B-type lectin domain, beta-trefoil fold, found in glucan endo-1,3-beta-glucosidase and similar proteins; Glucan endo-1,3-beta-glucosidase (EC 3.2.1.39), also called (1->3)-beta-glucan endohydrolase, or (1->3)-beta-glucanase, or laminarinase, belongs to the glycosyl hydrolase 64 (GH64) family. It catalyzes hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans. It has been implicated in the defense against fungal pathogens. Glucan endo-1,3-beta-glucosidase contains a C-terminal ricin B-type lectin domain with a beta-trefoil fold, characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

ricin B-type lectin domain, beta-trefoil fold, found in Drosophila melanogaster polypeptide N-acetylgalactosaminyltransferase 3 (Pgant3) and similar proteins; Pgant3, also called pp-GaNTase 3, protein-UDP acetylgalactosaminyltransferase 3, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 3, functions as a GalNAc transferase (EC 2.4.1.41) that catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Pgant3 can both act as a peptide transferase that transfers GalNAc onto unmodified peptide substrates, and as a glycopeptide transferase that requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. It prefers EA2 as a substrate and has weak activity toward Muc5AC-3, -13 and -3/13 substrates. Pgant3 plays a critical role in the regulation of integrin-mediated cell adhesion during wing development by influencing, via glycosylation, the secretion and localization of the integrin ligand Tig to the basal cell layer interface. It may have a role in protein O-glycosylation in the Golgi and thereby in establishing and/or maintaining a proper secretory apparatus structure. Together with Pgant35A, Pgant3 regulates integrin levels and activity-dependent integrin signaling at the synapse in neurons and muscles. Members of this subfamily contain a ricin B-type lectin domain at the C-terminus. The ricin B-type lectin domain shows a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) and similar proteins; GALNT7 (EC 2.4.1.41), also called polypeptide GalNAc transferase 7, GalNAc-T7, pp-GaNTase 7, protein-UDP acetylgalactosaminyltransferase 7, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 7, acts as glycopeptide transferase involved in O-linked oligosaccharide biosynthesis, which catalyzes the transfer of an N-acetyl-D-galactosamine residue to an already glycosylated peptide. In contrast to other proteins of the family, it does not act as a peptide transferase that transfers GalNAc onto serine or threonine residue on the protein receptor, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. Its appropriate peptide substrate remains unidentified. GALNT7 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif).

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3)-like subfamily; The GALNT3-like subfamily includes GALNT3, GALNT4, GALNT6 and GALNT12. They act as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT3 has activity toward HIV envelope glycoprotein gp120, EA2, Muc2 and Muc5. It probably glycosylates fibronectin in vivo as well as FGF23. It plays a central role in phosphate homeostasis. GALNT4 shows highest activity towards Muc7, EA2 and Muc2, with a lower activity compared to GALNT2. It glycosylates 'Thr-57' of SELPLG. GALNT6 may participate in the synthesis of oncofetal fibronectin. It has activity toward Muc1a, Muc2, EA2 and fibronectin peptides. GALNT12 has activity toward non-glycosylated peptides such as Muc5AC, Muc1a and EA2, and no detectable activity with non-glycosylated Muc2 and Muc7. It displays enzymatic activity toward the Gal-NAc-Muc5AC glycopeptide, but no detectable activity to mono-GalNAc-glycosylated Muc1a, Muc2, Muc7 and EA2. It may play an important role in the initial step of mucin-type oligosaccharide biosynthesis in digestive organs. Members of this family comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which are characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

484-554 1.79e-06

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 11 (GALNT11) and similar proteins; GALNT11 (EC 2.4.1.41), also called polypeptide GalNAc transferase 11, GalNAc-T11, pp-GaNTase 11, protein-UDP acetylgalactosaminyltransferase 11, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 11, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. It is involved in left/right asymmetry by mediating O-glycosylation of NOTCH1. O-glycosylation of NOTCH1 promotes its activation, modulating the balance between motile and immotile (sensory) cilia at the left-right organizer (LRO). GALNT11 displays the same enzyme activity toward MUC1, MUC4, and EA2 as GALNT1. It is not involved in glycosylation of erythropoietin (EPO). GALNT11 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

441-532 2.47e-06

ricin B-type lectin domain, beta-trefoil fold, found in Streptomyces olivaceoviridis endo-1,4-beta-xylanase and similar proteins; The family includes Streptomyces olivaceoviridis endo-1,4-beta-xylanase (XLN, EC 3.2.1.8), Streptomyces avermitilis beta-L-arabinopyranosidase (EC 3.2.1.185), and Streptomyces coelicolor extracellular exo-alpha-L-arabinofuranosidase (ABF, EC 3.2.1.55). XLN, also called xylanase, or 1,4-beta-D-xylan xylanohydrolase, belongs to the glycosyl hydrolase 10 (cellulase F) family. It contributes to hydrolyze hemicellulose, the major component of plant cell walls. XLN contains a (beta/alpha)8-barrel as a catalytic domain, a family 13 carbohydrate binding module (CBM13) as a xylan binding domain (XBD) and a Gly/Pro-rich linker between them. Beta-L-arabinopyranosidase belongs to the glycosyl hydrolase 27 (GH27) family. It has a GH27 catalytic domain, an antiparallel beta-domain containing Greek key motifs, another antiparallel beta-domain forming a jellyroll structure, and a CBM13 module. ScAraf62A, also called ABF, or arabinosidase, or arabinoxylan arabinofuranohydrolase, belongs to the glycosyl hydrolase 62 (GH62) family. It is involved in the degradation of xylan and is a key enzyme in the complete degradation of the plant cell wall. It has a specific arabinofuranose-debranching activity on xylan from gramineae. It acts synergistically with xylanases and binds specifically to xylan. ScAraf62A comprises a CBM13 module at its N-terminus and a catalytic domain at its C-terminus. This model corresponds to the CBM13 module, which is a ricin B-type lectin domain with a beta-trefoil fold, characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may contain a potential sugar-binding pocket.

ExoA is involved in the biosynthesis of succinoglycan; Succinoglycan Biosynthesis Protein ExoA catalyzes the formation of a beta-1,3 linkage of the second sugar (glucose) of the succinoglycan with the galactose on the lipid carrie. Succinoglycan is an acidic exopolysaccharide that is important for invasion of the nodules. Succinoglycan is a high-molecular-weight polymer composed of repeating octasaccharide units. These units are synthesized on membrane-bound isoprenoid lipid carriers, beginning with galactose followed by seven glucose molecules, and modified by the addition of acetate, succinate, and pyruvate. ExoA is a membrane protein with a transmembrance domain at c-terminus.

127-236 2.25e-05

DPM_DPG-synthase_like is a member of the Glycosyltransferase 2 superfamily; DPM1 is the catalytic subunit of eukaryotic dolichol-phosphate mannose (DPM) synthase. DPM synthase is required for synthesis of the glycosylphosphatidylinositol (GPI) anchor, N-glycan precursor, protein O-mannose, and C-mannose. In higher eukaryotes,the enzyme has three subunits, DPM1, DPM2 and DPM3. DPM is synthesized from dolichol phosphate and GDP-Man on the cytosolic surface of the ER membrane by DPM synthase and then is flipped onto the luminal side and used as a donor substrate. In lower eukaryotes, such as Saccharomyces cerevisiae and Trypanosoma brucei, DPM synthase consists of a single component (Dpm1p and TbDpm1, respectively) that possesses one predicted transmembrane region near the C terminus for anchoring to the ER membrane. In contrast, the Dpm1 homologues of higher eukaryotes, namely fission yeast, fungi, and animals, have no transmembrane region, suggesting the existence of adapter molecules for membrane anchoring. This family also includes bacteria and archaea DPM1_like enzymes. However, the enzyme structure and mechanism of function are not well understood. The UDP-glucose:dolichyl-phosphate glucosyltransferase (DPG_synthase) is a transmembrane-bound enzyme of the endoplasmic reticulum involved in protein N-linked glycosylation. This enzyme catalyzes the transfer of glucose from UDP-glucose to dolichyl phosphate. This protein family belongs to Glycosyltransferase 2 superfamily.

ricin B-type lectin domain, beta-trefoil fold, found in alpha-galactosidase A (AglA) and similar proteins; AglA (EC 3.2.1.22), also called melibiase A, hydrolyzes a variety of simple alpha-D-galactosides as well as more complex molecules such as oligosaccharides and polysaccharides. It belongs to the glycosyl hydrolase 27 (GH27) family. AglA contains an N-terminal GH27 catalytic domain, an alpha galactosidase C-terminal beta sandwich domain in the middle region, and a carbohydrate-binding domain at the C-terminus. The carbohydrate-binding domain is also known as a ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may contain a potential sugar-binding pocket.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) and similar proteins; GALNT7 (EC 2.4.1.41), also called polypeptide GalNAc transferase 7, GalNAc-T7, pp-GaNTase 7, protein-UDP acetylgalactosaminyltransferase 7, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 7, acts as glycopeptide transferase involved in O-linked oligosaccharide biosynthesis, which catalyzes the transfer of an N-acetyl-D-galactosamine residue to an already glycosylated peptide. In contrast to other proteins of the family, it does not act as a peptide transferase that transfers GalNAc onto serine or threonine residue on the protein receptor, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. Its appropriate peptide substrate remains unidentified. GALNT7 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

478-553 1.83e-04

ricin B-type lectin domain, beta-trefoil fold, found in bacterial hemolysin and similar proteins; Bacterial hemolysins are exotoxins that attack blood cell membranes and cause cytolysis by forming heptameric pores in target host membranes. After binding to target membranes, the protein assembles into a heptameric pre-pore complex. Proteolytic cleavage triggers a conformation change that is required for membrane insertion and pore formation. Hemolysin may be called "cytolysin" or "cytolytic toxin", according to a specific action for certain cells. For example, this subfamily includes Vibrio vulnificus cytolysin that attack blood cell membranes and cause cell rupture, thereby liberating hemoglobins. Members of this subfamily contain a ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may harbor a putative sugar-binding pocket.

441-553 2.74e-04

ricin B-type lectin domain, beta-trefoil fold, found in the macrophage mannose receptor (MRC) family; The MRC family includes MRC1-2, receptor-type tyrosine-protein phosphatase beta (PTPRB) isoform e, secretory phospholipase A2 receptor (PLA2R1), and lymphocyte antigen 75 (Ly-75). MRC1 mediates the endocytosis of glycoproteins by macrophages. It binds both sulfated and non-sulfated polysaccharide chains, and acts as a phagocytic receptor for bacteria, fungi, and other pathogens. It also acts as a receptor for Dengue virus envelope protein E. MRC2 may play a role as an endocytotic lectin receptor displaying calcium-dependent lectin activity. It internalizes glycosylated ligands from the extracellular space for release in an endosomal compartment via clathrin-mediated endocytosis. It may be involved in plasminogen activation system controlling the extracellular level of PLAUR/PLAU, and thus may regulate protease activity at the cell surface. It may contribute to cellular uptake, remodeling, and degradation of extracellular collagen matrices. It may play a role during cancer progression as well as in other chronic tissue destructive diseases acting on collagen turnover. It may participate in remodeling of extracellular matrix cooperating with the matrix metalloproteinases (MMPs). PTPRB (EC 3.1.3.48), also called protein-tyrosine phosphatase beta, plays an important role in blood vessel remodeling and angiogenesis. It is not necessary for the initial formation of the blood vessels but is essential for their maintenance and remodeling. It is also essential for the maintenance of endothelial cell contact integrity and for the adhesive function of VE-cadherin in endothelial cells that requires the presence of plakoglobin. PLA2R1 is a receptor for secretory phospholipase A2 (sPLA2). It acts as a receptor for phospholipase sPLA2-IB/PLA2G1B but not sPLA2-IIA/PLA2G2A. It can also bind to snake PA2-like toxins. It may be involved in responses in proinflammatory cytokine productions during endotoxic shock. It also has endocytic properties and rapidly internalizes sPLA2 ligands, which is particularly important for the clearance of extracellular sPLA2s to protect their potent enzymatic activities. Ly-75 acts as an endocytic receptor to direct captured antigens from the extracellular space to a specialized antigen-processing compartment. It causes reduced proliferation of B-lymphocytes. All family members contain a ricin B-type lectin domain at the N-terminus. The ricin B-type lectin domain shows a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may harbor a sugar-binding pocket. One member of this family, MRC1, is missing the gamma subdomain.

GALNT2 has a broad spectrum of substrates for peptides such as EA2, Muc5AC, Muc1a, Muc1b. It is probably involved in O-linked glycosylation of the immunoglobulin A1 (IgA1) hinge region. It is also involved in O-linked glycosylation of APOC-III, ANGPTL3 and PLTP. It participates in the regulation of HDL-C metabolism. GALNT2 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

Bacterial DPM1_like enzymes are related to eukaryotic DPM1; A family of bacterial enzymes related to eukaryotic DPM1; Although the mechanism of eukaryotic enzyme is well studied, the mechanism of the bacterial enzymes is not well understood. The eukaryotic DPM1 is the catalytic subunit of eukaryotic Dolichol-phosphate mannose (DPM) synthase. DPM synthase is required for synthesis of the glycosylphosphatidylinositol (GPI) anchor, N-glycan precursor, protein O-mannose, and C-mannose. The enzyme has three subunits, DPM1, DPM2 and DPM3. DPM is synthesized from dolichol phosphate and GDP-Man on the cytosolic surface of the ER membrane by DPM synthase and then is flipped onto the luminal side and used as a donor substrate. This protein family belongs to Glycosyltransferase 2 superfamily.

ricin B-type lectin domain, beta-trefoil fold, found in cytolethal distending toxin subunit A (CdtA) and similar proteins; Cytolethal distending toxins (CDTs) are cytotoxins which induce host cell distension, growth arrest in G2/M phase, nucleus swelling, and chromatin fragmentation in HeLa cells. CDT is a heterotrimer consisting of the three subunits, CdtA, CdtB, and CdtC. CdtA, along with CdtC, probably forms a heterodimeric subunit required for the delivery of nuclease CdtB. CdtA contains a ricin B-type lectin domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may harbor a sugar-binding pocket.

first ricin B-type lectin domain, beta-trefoil fold, found in type II ribosome-inactivating proteins (RIPs); Type II ribosome-inactivating proteins (RIPs) inhibit translation in eukaryotes by irreversibly inactivating the 28S rRNA and preventing the binding of elongation factor II to the ribosome. They consist of a catalytic A-chain which has rRNA N-glycosidase activity and a lectin B-chain containing two ricin B-type lectin domains with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The lectin chain facilitates the internalization of the catalytic chain on binding to the cell surface. The two chains are connected by a disulfide bridge. This model corresponds to the first ricin B-type lectin domain. Members of this subfamily includes Ricinus communis ricin, bitter gourd (Momordica charantia) seed lectin (BGSL), snake gourd (Trichosanthes anguina) seed lectin (SGSL), Sambucus ebulus ebulin I, Sambucus nigra nigrin b (also known as agglutinin V or SNAV), SNAI (also known as agglutinin I), SNAI' and SNAIf, Abrus precatorius abrin (ABR) and agglutinin-I (AAG), and Viscum album beta-galactoside-specific lectins 1-4 (also known as mistletoe lectins or MLs).

UDP-glucose LOS-beta-1,4 glucosyltransferase is required for biosynthesis of lipooligosaccharide; UDP-glucose: lipooligosaccharide (LOS) beta-1-4-glucosyltransferase catalyzes the addition of the first residue, glucose, of the lacto-N-neotetrase structure to HepI of the LOS inner core. LOS is the major constituent of the outer leaflet of the outer membrane of gram-positive bacteria. It consists of a short oligosaccharide chain of variable composition (alpha chain) attached to a branched inner core which is lined in turn to lipid A. Beta 1,4 glucosyltransferase is required to attach the alpha chain to the inner core.

469-516 2.54e-03

ricin B-type lectin domain, beta-trefoil fold, found in Drosophila melanogaster polypeptide N-acetylgalactosaminyltransferase 3 (Pgant3) and similar proteins; Pgant3, also called pp-GaNTase 3, protein-UDP acetylgalactosaminyltransferase 3, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 3, functions as a GalNAc transferase (EC 2.4.1.41) that catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Pgant3 can both act as a peptide transferase that transfers GalNAc onto unmodified peptide substrates, and as a glycopeptide transferase that requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. It prefers EA2 as a substrate and has weak activity toward Muc5AC-3, -13 and -3/13 substrates. Pgant3 plays a critical role in the regulation of integrin-mediated cell adhesion during wing development by influencing, via glycosylation, the secretion and localization of the integrin ligand Tig to the basal cell layer interface. It may have a role in protein O-glycosylation in the Golgi and thereby in establishing and/or maintaining a proper secretory apparatus structure. Together with Pgant35A, Pgant3 regulates integrin levels and activity-dependent integrin signaling at the synapse in neurons and muscles. Members of this subfamily contain a ricin B-type lectin domain at the C-terminus. The ricin B-type lectin domain shows a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site.
