Rossmann-fold NAD(P)(+)-binding proteins; A large family of proteins that share a Rossmann-fold NAD(P)H/NAD(P)(+) binding (NADB) domain. The NADB domain is found in numerous dehydrogenases of metabolic pathways such as glycolysis, and many other redox enzymes. NAD binding involves numerous hydrogen-bonds and van der Waals contacts, in particular H-bonding of residues in a turn between the first strand and the subsequent helix of the Rossmann-fold topology. Characteristically, this turn exhibits a consensus binding pattern similar to GXGXXG, in which the first 2 glycines participate in NAD(P)-binding, and the third facilitates close packing of the helix to the beta-strand. Typically, proteins in this family contain a second domain in addition to the NADB domain, which is responsible for specifically binding a substrate and catalyzing a particular enzymatic reaction.

9-340 1.84e-59

phenylcoumaran benzylic ether reductase (PCBER) like, atypical (a) SDRs; PCBER and pinoresinol-lariciresinol reductases are NADPH-dependent aromatic alcohol reductases, and are atypical members of the SDR family. Other proteins in this subgroup are identified as eugenol synthase. These proteins contain an N-terminus characteristic of NAD(P)-binding proteins and a small C-terminal domain presumed to be involved in substrate binding, but they do not have the conserved active site Tyr residue typically found in SDRs. Numerous other members have unknown functions. The glycine rich NADP-binding motif in this subgroup is of 2 forms: GXGXXG and G[GA]XGXXG; it tends to be atypical compared with the forms generally seen in classical or extended SDRs. The usual SDR active site tetrad is not present, but a critical active site Lys at the usual SDR position has been identified in various members, though other charged and polar residues are found at this position in this subgroup. Atypical SDR-related proteins retain the Rossmann fold of the SDRs, but have limited sequence identity and generally lack the catalytic properties of the archetypical members. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. In addition to the Rossmann fold core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids, and typically have a TGXXGXXG cofactor binding motif. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

atypical (a) SDRs, subgroup 5; This subgroup contains atypical SDRs, some of which are identified as putative NAD(P)-dependent epimerases, one as a putative NAD-dependent epimerase/dehydratase. Atypical SDRs are distinct from classical SDRs. Members of this subgroup have a glycine-rich NAD(P)-binding motif that is very similar to the extended SDRs, GXXGXXG, and binds NADP. Generally, this subgroup has poor conservation of the active site tetrad; however, individual sequences do contain matches to the YXXXK active site motif, the upstream Ser, and there is a highly conserved Asp in place of the usual active site Asn throughout the subgroup. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. In addition to the Rossmann fold core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids, and typically have a TGXXGXXG cofactor binding motif. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

Members of this subgroup have a glycine-rich NAD(P)-binding motif consensus that matches the extended SDRs, TGXXGXXG, but lacks the characteristic active site residues of the SDRs. This subgroup has basic residues (HXXXR) in place of the active site motif YXXXK, these may have a catalytic role. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs.

uncharacterized subgroup of aldehyde reductase and flavonoid reductase related proteins, extended (e) SDRs; This subgroup contains proteins of unknown function related to aldehyde reductase and flavonoid reductase of the extended SDR-type. Aldehyde reductase I (aka carbonyl reductase) is an NADP-binding SDR; it has an NADP-binding motif consensus that is slightly different from the canonical SDR form and lacks the Asn of the extended SDR active site tetrad. Aldehyde reductase I catalyzes the NADP-dependent reduction of ethyl 4-chloro-3-oxobutanoate to ethyl (R)-4-chloro-3-hydroxybutanoate. The related flavonoid reductases act in the NADP-dependent reduction of flavonoids, ketone-containing plant secondary metabolites. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids.

Human BVR-B catalyzes the reduction of FMN, FAD, and riboflavin. Recognition of flavin occurs mostly by hydrophobic interactions, accounting for the broad substrate specificity. Atypical SDRs are distinct from classical SDRs. BVR-B does not share the key catalytic triad, or conserved tyrosine typical of SDRs. The glycine-rich NADP-binding motif of BVR-B is GXXGXXG, which is similar but not identical to the pattern seen in extended SDRs. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. In addition to the Rossmann fold core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids, and typically have a TGXXGXXG cofactor binding motif. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

triphenylmethane reductase (TMR)-like proteins, NMRa-like, atypical (a) SDRs; TMR is an atypical NADP-binding protein of the SDR family. It lacks the active site residues of the SDRs but has a glycine rich NAD(P)-binding motif that matches the extended SDRs. Proteins in this subgroup however, are more similar in length to the classical SDRs. TMR was identified as a reducer of triphenylmethane dyes, important environmental pollutants. This subgroup also includes Escherichia coli NADPH-dependent quinine oxidoreductase (QOR2), which catalyzes two-electron reduction of quinone; but is unlikely to play a major role in protecting against quinone cytotoxicity. Atypical SDRs are distinct from classical SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. In addition to the Rossmann fold core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids, and typically have a TGXXGXXG cofactor binding motif. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

NmrA (a transcriptional regulator) and HSCARG (an NADPH sensor) like proteins, atypical (a) SDRs; NmrA and HSCARG like proteins. NmrA is a negative transcriptional regulator of various fungi, involved in the post-translational modulation of the GATA-type transcription factor AreA. NmrA lacks the canonical GXXGXXG NAD-binding motif and has altered residues at the catalytic triad, including a Met instead of the critical Tyr residue. NmrA may bind nucleotides but appears to lack any dehydrogenase activity. HSCARG has been identified as a putative NADP-sensing molecule, and redistributes and restructures in response to NADPH/NADP ratios.

Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

10-83 4.54e-05

Pseudomonas fluorescens MupV-like, extended (e) SDRs; This subgroup of extended SDR family domains have the characteristic active site tetrad and a well-conserved NAD(P)-binding motif. This subgroup is not well characterized, its members are annotated as having a variety of putative functions. One characterized member is Pseudomonas fluorescens MupV a protein involved in the biosynthesis of Mupirocin, a polyketide-derived antibiotic. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

9-115 7.63e-05

CC3(TIP30)-like, atypical (a) SDRs; Atypical SDRs in this subgroup include CC3 (also known as TIP30) which is implicated in tumor suppression. Atypical SDRs are distinct from classical SDRs. Members of this subgroup have a glycine rich NAD(P)-binding motif that resembles the extended SDRs, and have an active site triad of the SDRs (YXXXK and upstream Ser), although the upstream Asn of the usual SDR active site is substituted with Asp. For CC3, the Tyr of the triad is displaced compared to the usual SDRs and the protein is monomeric, both these observations suggest that the usual SDR catalytic activity is not present. NADP appears to serve an important role as a ligand, and may be important in the interaction with other macromolecules. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering).

9-81 1.24e-04

N-terminal NAD(P)-binding domain of dihydrodipicolinate reductase (DHDPR) and similar proteins; DHDPR (EC 1.17.1.8), also called 4-hydroxy-tetrahydrodipicolinate reductase, or HTPA reductase, is a product of an essential gene referred to as dapB. It catalyzes the NAD(P)H-dependent reduction of 2,3-dihydrodipicolinate (DHDP) to 2,3,4,5-tetrahydrodipicolinate (THDP). DHDPR could also function as a dehydratase in addition to the role of a nucleotide dependent reductase. DHDPR is a component of the biosynthetic pathway that generates meso-diaminopimelate, a component of bacterial cell walls, and the amino acid L-lysine in various bacteria, archaea, cyanobacteria and higher plants. The enzyme is a homotetramer where each monomer is composed of two domains, an N-terminal NAD(P)-binding domain which forms a Rossmann fold, and a C-terminal substrate-binding domain that forms an open, mixed alpha-beta sandwich.

N-terminal NAD(P)-binding domain of USG-1 protein and similar proteins; The family includes Escherichia coli USG-1 protein, Pseudomonas aeruginosa USG-1 homolog proteins and similar proteins. Although their biological function remains unknown, they are homologs to aspartate beta-semialdehyde dehydrogenase (ASADH) which contains an N-terminal Rossmann fold NAD(P) binding domain and a C-terminal glyceraldehyde-3-phosphate dehydrogenase (GAPDH)-like domain. However, USG-1 proteins lack the conserved active site residues of the ASADH protein C-terminal domain.

dTDP-6-deoxy-L-lyxo-4-hexulose reductase and related proteins, extended (e) SDRs; dTDP-6-deoxy-L-lyxo-4-hexulose reductase, an extended SDR, synthesizes dTDP-L-rhamnose from alpha-D-glucose-1-phosphate, providing the precursor of L-rhamnose, an essential cell wall component of many pathogenic bacteria. This subgroup has the characteristic active site tetrad and NADP-binding motif. This subgroup also contains human MAT2B, the regulatory subunit of methionine adenosyltransferase (MAT); MAT catalyzes S-adenosylmethionine synthesis. The human gene encoding MAT2B encodes two major splicing variants which are induced in human cell liver cancer and regulate HuR, an mRNA-binding protein which stabilizes the mRNA of several cyclins, to affect cell proliferation. Both MAT2B variants include this extended SDR domain. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide.

aldehyde reductase, extended (e) SDRs; This subgroup contains aldehyde reductase of the extended SDR-type and related proteins. Aldehyde reductase I (aka carbonyl reductase) is an NADP-binding SDR; it has an NADP-binding motif consensus that is slightly different from the canonical SDR form and lacks the Asn of the extended SDR active site tetrad. Aldehyde reductase I catalyzes the NADP-dependent reduction of ethyl 4-chloro-3-oxobutanoate to ethyl (R)-4-chloro-3-hydroxybutanoate. Extended SDRs are distinct from classical SDRs.

9-127 4.51e-04

N-terminal NAD(P)-binding domain of actinobacterial N-acetyl-gamma-glutamyl-phosphate reductase (actinobacAGPR) and similar proteins; AGPR (EC 1.2.1.38), also called N-acetyl-glutamate semialdehyde dehydrogenase, or NAGSA dehydrogenase, catalyzes the third step in the biosynthesis of arginine from glutamate, the NADPH-dependent reduction of N-acetyl-5-glutamyl phosphate into N-acetylglutamate 5-semialdehyde. In bacteria it is a monofunctional protein of 35 to 38kDa (gene argC). There are two related families (type 1 and type 2) of N-acetyl-gamma-glutamyl-phosphate reductase, which differ by phylogeny, similarity clustering, and gap architecture in a multiple sequence alignment. The family includes N-acetyl-gamma-glutamyl-phosphate reductases mainly from actinobacteria. They belong to the type 1 AGPR family. Members in this family contain an N-terminal Rossmann fold NAD(P)-binding domain and a C-terminal glyceraldehyde-3-phosphate dehydrogenase (GAPDH)-like domain.

9-109 1.26e-03

NADH dehydrogenase (ubiquinone) 1 alpha subcomplex, subunit 9, 39 kDa, (NDUFA9) -like, atypical (a) SDRs; This subgroup of extended SDR-like proteins are atypical SDRs. They have a glycine-rich NAD(P)-binding motif similar to the typical SDRs, GXXGXXG, and have the YXXXK active site motif (though not the other residues of the SDR tetrad). Members identified include NDUFA9 (mitochondrial) and putative nucleoside-diphosphate-sugar epimerase. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. In addition to the Rossmann fold core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids, and typically have a TGXXGXXG cofactor binding motif. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

atypical (a) SDRs, subgroup 1; Atypical SDRs in this subgroup are poorly defined and have been identified putatively as isoflavones reductase, sugar dehydratase, mRNA binding protein etc. Atypical SDRs are distinct from classical SDRs. Members of this subgroup retain the canonical active site triad (though not the upstream Asn found in most SDRs) but have an unusual putative glycine-rich NAD(P)-binding motif, GGXXXXG, in the usual location. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Atypical SDRs include biliverdin IX beta reductase (BVR-B,aka flavin reductase), NMRa (a negative transcriptional regulator of various fungi), progesterone 5-beta-reductase like proteins, phenylcoumaran benzylic ether and pinoresinol-lariciresinol reductases, phenylpropene synthases, eugenol synthase, triphenylmethane reductase, isoflavone reductases, and others.

UDP-glucose 4 epimerase, subgroup 4, extended (e) SDRs; UDP-glucose 4 epimerase (aka UDP-galactose-4-epimerase), is a homodimeric extended SDR. It catalyzes the NAD-dependent conversion of UDP-galactose to UDP-glucose, the final step in Leloir galactose synthesis. This subgroup is comprised of bacterial proteins, and includes the Staphylococcus aureus capsular polysaccharide Cap5N, which may have a role in the synthesis of UDP-N-acetyl-d-fucosamine. This subgroup has the characteristic active site tetrad and NAD-binding motif of the extended SDRs. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif.
