P-loop containing Nucleoside Triphosphate Hydrolases; Members of the P-loop NTPase domain superfamily are characterized by a conserved nucleotide phosphate-binding motif, also referred to as the Walker A motif (GxxxxGK[S/T], where x is any residue), and the Walker B motif (hhhh[D/E], where h is a hydrophobic residue). The Walker A and B motifs bind the beta-gamma phosphate moiety of the bound nucleotide (typically ATP or GTP) and the Mg2+ cation, respectively. The P-loop NTPases are involved in diverse cellular functions, and they can be divided into two major structural classes: the KG (kinase-GTPase) class which includes Ras-like GTPases and its circularly permutated YlqF-like; and the ASCE (additional strand catalytic E) class which includes ATPase Binding Cassette (ABC), DExD/H-like helicases, 4Fe-4S iron sulfur cluster binding proteins of NifH family, RecA-like F1-ATPases, and ATPases Associated with a wide variety of Activities (AAA). Also included are a diverse set of nucleotide/nucleoside kinase families.

Elongation Factor 1-alpha (EF1-alpha) protein family; EF1 is responsible for the GTP-dependent binding of aminoacyl-tRNAs to the ribosomes. EF1 is composed of four subunits: the alpha chain which binds GTP and aminoacyl-tRNAs, the gamma chain that probably plays a role in anchoring the complex to other cellular components and the beta and delta (or beta') chains. This subfamily is the alpha subunit, and represents the counterpart of bacterial EF-Tu for the archaea (aEF1-alpha) and eukaryotes (eEF1-alpha). eEF1-alpha interacts with the actin of the eukaryotic cytoskeleton and may thereby play a role in cellular transformation and apoptosis. EF-Tu can have no such role in bacteria. In humans, the isoform eEF1A2 is overexpressed in 2/3 of breast cancers and has been identified as a putative oncogene. This subfamily also includes Hbs1, a G protein known to be important for efficient growth and protein synthesis under conditions of limiting translation initiation in yeast, and to associate with Dom34. It has been speculated that yeast Hbs1 and Dom34 proteins may function as part of a complex with a role in gene expression.

2-67 | 5.94e-09 | ||
sulfate adenylyltransferase, large subunit; Metabolic assimilation of sulfur from inorganic sulfate, requires sulfate activation by coupling to a nucleoside, for the production of high-energy nucleoside phosphosulfates. This pathway appears to be similar in all prokaryotic organisms. Activation is first achieved through sulfation of sulfate with ATP by sulfate adenylyltransferase (ATP sulfurylase) to produce 5'-phosphosulfate (APS), coupled by GTP hydrolysis. Subsequently, APS is phosphorylated by an APS kinase to produce 3'-phosphoadenosine-5'-phosphosulfate (PAPS). In Escherichia coli, ATP sulfurylase is a heterodimer composed of two subunits encoded by cysD and cysN, with APS kinase encoded by cysC. These genes are located in a unidirectionally transcribed gene cluster, and have been shown to be required for the synthesis of sulfur-containing amino acids. Homologous to this E.coli activation pathway are nodPQH gene products found among members of the Rhizobiaceae family. These gene products have been shown to exhibit ATP sulfurase and APS kinase activity, yet are involved in Nod factor sulfation, and sulfation of other macromolecules. With members of the Rhizobiaceae family, nodQ often appears as a fusion of cysN (large subunit of ATP sulfurase) and cysC (APS kinase).

CysN, together with protein CysD, forms the ATP sulfurylase (ATPS) complex; CysN_ATPS subfamily. CysN, together with protein CysD, form the ATP sulfurylase (ATPS) complex in some bacteria and lower eukaryotes. ATPS catalyzes the production of ATP sulfurylase (APS) and pyrophosphate (PPi) from ATP and sulfate. CysD, which catalyzes ATP hydrolysis, is a member of the ATP pyrophosphatase (ATP PPase) family. CysN hydrolysis of GTP is required for CysD hydrolysis of ATP; however, CysN hydrolysis of GTP is not dependent on CysD hydrolysis of ATP. CysN is an example of lateral gene transfer followed by acquisition of new function. In many organisms, an ATPS exists which is not GTP-dependent and shares no sequence or structural similarity to CysN. Pssm-ID: 206729 [Multi-domain] Cd Length: 209 Bit Score: 55.65 E-value: 3.33e-11

LepA also known as Elongation Factor 4 (EF4); LepA (also known as elongation factor 4, EF4) belongs to the GTPase family and exhibits significant homology to the translation factors EF-G and EF-Tu, indicating its possible involvement in translation and association with the ribosome. LepA is ubiquitous in bacteria and eukaryota (e.g. yeast GUF1p), but is missing from archaea. This pattern of phyletic distribution suggests that LepA evolved through a duplication of the EF-G gene in bacteria, followed by early transfer into the eukaryotic lineage, most likely from the promitochondrial endosymbiont. Yeast GUF1p is not essential and mutant cells did not reveal any marked phenotype. Pssm-ID: 206677 [Multi-domain] Cd Length: 179 Bit Score: 46.76 E-value: 5.37e-08

1-74 | 2.11e-04 | ||
Elongation factor G (EF-G) family involved in both the elongation and ribosome recycling phases of protein synthesis; Translocation is mediated by EF-G (also called translocase). The structure of EF-G closely resembles that of the complex between EF-Tu and tRNA. This is an example of molecular mimicry; a protein domain evolved so that it mimics the shape of a tRNA molecule. EF-G in the GTP form binds to the ribosome, primarily through the interaction of its EF-Tu-like domain with the 50S subunit. The binding of EF-G to the ribosome in this manner stimulates the GTPase activity of EF-G. On GTP hydrolysis, EF-G undergoes a conformational change that forces its arm deeper into the A site on the 30S subunit. To accommodate this domain, the peptidyl-tRNA in the A site moves to the P site, carrying the mRNA and the deacylated tRNA with it. The ribosome may be prepared for these rearrangements by the initial binding of EF-G as well. The dissociation of EF-G leaves the ribosome ready to accept the next aminoacyl-tRNA into the A site. This group contains both eukaryotic and bacterial members. Pssm-ID: 206673 [Multi-domain] Cd Length: 270 Bit Score: 37.47 E-value: 2.11e-04

2-57 | 2.85e-04 | ||
Elongation Factor 2 (EF2) in archaea and eukarya; Translocation requires hydrolysis of a molecule of GTP and is mediated by EF-G in bacteria and by eEF2 in eukaryotes. The eukaryotic elongation factor eEF2 is a GTPase involved in the translocation of the peptidyl-tRNA from the A site to the P site on the ribosome. The 95-kDa protein is highly conserved, with 60% amino acid sequence identity between the human and yeast proteins. Two major mechanisms are known to regulate protein elongation and both involve eEF2. First, eEF2 can be modulated by reversible phosphorylation. Increased levels of phosphorylated eEF2 reduce elongation rates presumably because phosphorylated eEF2 fails to bind the ribosomes. Treatment of mammalian cells with agents that raise the cytoplasmic Ca2+ and cAMP levels reduce elongation rates by activating the kinase responsible for phosphorylating eEF2. In contrast, treatment of cells with insulin increases elongation rates by promoting eEF2 dephosphorylation. Second, the protein can be post-translationally modified by ADP-ribosylation. Various bacterial toxins perform this reaction after modification of a specific histidine residue to diphthamide, but there is evidence for endogenous ADP ribosylase activity. Similar to the bacterial toxins, it is presumed that modification by the endogenous enzyme also inhibits eEF2 activity.

Tet(M)-like family includes Tet(M), Tet(O), Tet(W), and OtrA, containing tetracycline resistant proteins; Tet(M), Tet(O), Tet(W), and OtrA are tetracycline resistance genes found in Gram-positive and Gram-negative bacteria. Tetracyclines inhibit protein synthesis by preventing aminoacyl-tRNA from binding to the ribosomal acceptor site. This subfamily contains tetracycline resistance proteins that function through ribosomal protection and are typically found on mobile genetic elements, such as transposons or plasmids, and are often conjugative. Ribosomal protection proteins are homologous to the elongation factors EF-Tu and EF-G. EF-G and Tet(M) compete for binding on the ribosomes. Tet(M) has a higher affinity than EF-G, suggesting these two proteins may have overlapping binding sites and that Tet(M) must be released before EF-G can bind. Tet(M) and Tet(O) have been shown to have ribosome-dependent GTPase activity. These proteins are part of the GTP translation factor family, which includes EF-G, EF-Tu, EF2, LepA, and SelB.
