Title:
ケト化合物の立体選択的酵素還元法
Document Type and Number:
Japanese Patent JP5852885
Kind Code:
B2
Abstract:
Stereoselective (preferably enantioselective) enzymatic reduction of ketocompounds to their corresponding chiral hydroxycompounds, comprises reducing the ketocompounds with an oxidoreductase, where: a polypeptide is used for the reduction of the ketocompounds; and the polypeptide includes the short-chain oxidoreductase and characteristics of e.g. (a) a N-terminal Rossmann-Fold GlyxxxGlyxGly, (b) a AsnAsnAlaGly-motif at position 86, (c) a catalytic triad consisting of Ser 139, Tyr 152 and Lys 156, and (d) a negatively charged amino acid residue at position 37.
