Name  Aldo/keto reductase subgroup Short Name  Aldo/keto_reductase_subgr
Type  Family Description  The aldo-keto reductase family includes a number of related monomeric NADPH-dependent oxidoreductases, such as aldehyde reductase, aldosereductase, prostaglandin F synthase, xylose reductase, rho crystallin, andmany others []. All possess a similar structure, with a beta-alpha-beta fold characteristic of nucleotide binding proteins [].The fold comprises a parallel beta-8/alpha-8-barrel, which contains a novel NADP-binding motif. The binding site is located in a large,deep, elliptical pocket in the C-terminal end of the beta sheet, the substrate being bound in an extended conformation. The hydrophobicnature of the pocket favours aromatic and apolar substrates over highlypolar ones [].Binding of the NADPH coenzyme causes a massiveconformational change, reorienting a loop, effectively locking thecoenzyme in place. This binding is more similar to FAD- than toNAD(P)-binding oxidoreductases [].
