nucleotide sugar dehydrogenase; Enzymes in this family catalyze the NAD-dependent alcohol-to-acid oxidation of nucleotide-linked sugars. Examples include UDP-glucose 6-dehydrogenase (1.1.1.22), GDP-mannose 6-dehydrogenase (1.1.1.132), UDP-N-acetylglucosamine 6-dehydrogenase (1.1.1.136), UDP-N-acetyl-D-galactosaminuronic acid dehydrogenase, and UDP-N-acetyl-D-mannosaminuronic acid dehydrogenase. These enzymes are most often involved in the biosynthesis of polysaccharides and are often found in operons devoted to that purpose. All of these enzymes contain three Pfam domains, pfam03721, pfam00984, and pfam03720 for the N-terminal, central, and C-terminal regions respectively.

atypical (a) SDRs, subgroup 4; Atypical SDRs in this subgroup are poorly defined, one member is identified 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 related to, but is different from, the archetypical SDRs, GXGXXG. This subgroup also lacks most of the characteristic active site residues of the SDRs; however, the upstream Ser is present at the usual place, and some potential catalytic residues are present in place of the usual YXXXK active site motif. 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.

Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxy acid dehydrogenase family; Formate dehydrogenase, D-specific 2-hydroxy acid dehydrogenase, Phosphoglycerate Dehydrogenase, Lactate dehydrogenase, Thermostable Phosphite Dehydrogenase, and Hydroxy(phenyl)pyruvate reductase, among others, share a characteristic arrangement of 2 similar subdomains of the alpha/beta Rossmann fold NAD+ binding form. 2-hydroxyacid dehydrogenases are enzymes that catalyze the conversion of a wide variety of D-2-hydroxy acids to their corresponding keto acids. The general mechanism is (R)-lactate + acceptor to pyruvate + reduced acceptor. The NAD+ binding domain is inserted within the linear sequence of the mostly N-terminal catalytic domain, which has a similar domain structure to the internal NAD binding domain. Structurally, these domains are connected by extended alpha helices and create a cleft in which NAD is bound, primarily to the C-terminal portion of the 2nd (internal) domain. Some related proteins have similar structural subdomain but with a tandem arrangement of the catalytic and NAD-binding subdomains in the linear sequence. Formate dehydrogenase (FDH) catalyzes the NAD+-dependent oxidation of formate ion to carbon dioxide with the concomitant reduction of NAD+ to NADH. FDHs of this family contain no metal ions or prosthetic groups. Catalysis occurs though direct transfer of hydride ion to NAD+ without the stages of acid-base catalysis typically found in related dehydrogenases. FDHs are found in all methylotrophic microorganisms in energy production and in the stress responses of plants. Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxyacid dehydrogenase superfamily include groups such as formate dehydrogenase, glycerate dehydrogenase, L-alanine dehydrogenase, and S-Adenosylhomocysteine Hydrolase, among others. While many members of this family are dimeric, alanine DH is hexameric and phosphoglycerate DH is tetrameric.
