2-hydroxy-3-oxopropionate reductase; This model represents 2-hydroxy-3-oxopropionate reductase (EC 1.1.1.60), also called tartronate semialdehyde reductase. It follows glyoxylate carboligase and precedes glycerate kinase in D-glycerate pathway of glyoxylate degradation. The eventual product, 3-phosphoglycerate, is an intermediate of glycolysis and is readily metabolized. Tartronic semialdehyde, the substrate of this enzyme, may also come from other pathways, such as D-glucarate catabolism.

NADP-binding domain of glutamyl-tRNA reductase; Glutamyl-tRNA reductase catalyzes the conversion of glutamyl-tRNA to glutamate-1-semialdehyde, initiating the synthesis of tetrapyrrole. Whereas tRNAs are generally associated with peptide bond formation in protein translation, here the tRNA activates glutamate in the initiation of tetrapyrrole biosynthesis in archaea, plants and many bacteria. In the first step, activated glutamate is reduced to glutamate-1-semi-aldehyde via the NADPH dependent glutamyl-tRNA reductase. Glutamyl-tRNA reductase forms a V-shaped dimer. Each monomer has 3 domains: an N-terminal catalytic domain, a classic nucleotide binding domain, and a C-terminal dimerization domain. Although the representative structure 1GPJ lacks a bound NADPH, a theoretical binding pocket has been described. (PMID 11172694). Amino acid dehydrogenase (DH)-like NAD(P)-binding domains are members of the Rossmann fold superfamily and include glutamate, leucine, and phenylalanine DHs, methylene tetrahydrofolate DH, methylene-tetrahydromethanopterin DH, methylene-tetrahydropholate DH/cyclohydrolase, Shikimate DH-like proteins, malate oxidoreductases, and glutamyl tRNA reductase. Amino acid DHs catalyze the deamination of amino acids to keto acids with NAD(P)+ as a cofactor. The NAD(P)-binding Rossmann fold superfamily includes a wide variety of protein families including NAD(P)- binding domains of alcohol DHs, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate DH, lactate/malate DHs, formate/glycerate DHs, siroheme synthases, 6-phosphogluconate DH, amino acid DHs, repressor rex, NAD-binding potassium channel domain, CoA-binding, and ornithine cyclodeaminase-like domains. These domains have an alpha-beta-alpha configuration. NAD binding involves numerous hydrogen and van der Waals contacts.

3-hydroxyisobutyrate dehydrogenase; 3-hydroxyisobutyrate dehydrogenase is an enzyme that catalyzes the NAD+-dependent oxidation of 3-hydroxyisobutyrate to methylmalonate semialdehyde of the valine catabolism pathway. In Pseudomonas aeruginosa, 3-hydroxyisobutyrate dehydrogenase (mmsB) is co-induced with methylmalonate-semialdehyde dehydrogenase (mmsA) when grown on medium containing valine as the sole carbon source. The positive transcriptional regulator of this operon (mmsR) is located upstream of these genes and has been identified as a member of the XylS/AraC family of transcriptional regulators. 3-hydroxyisobutyrate dehydrogenase shares high sequence homology to the characterized 3-hydroxyisobutyrate dehydrogenase from rat liver with conservation of proposed NAD+ binding residues at the N-terminus (G-8,10,13,24 and D-31). This enzyme belongs to the 3-hydroxyacid dehydrogenase family, sharing a common evolutionary origin and enzymatic mechanism with 6-phosphogluconate. HIBADH exhibits sequence similarity to the NAD binding domain of 6-phosphogluconate dehydrogenase above trusted (pfam03446). [Energy metabolism, Amino acids and amines]

NAD-binding of NADP-dependent 3-hydroxyisobutyrate dehydrogenase; 3-Hydroxyisobutyrate is a central metabolite in the valine catabolic pathway, and is reversibly oxidized to methylmalonate semi-aldehyde by a specific dehydrogenase belonging to the 3-hydroxyacid dehydrogenase family. The reaction is NADP-dependent and this region of the enzyme binds NAD. The NAD-binding domain of 6-phosphogluconate dehydrogenase adopts an alpha helical structure.
