An oxidoreductase (I) that, in presence of NADPH and water, reduces a 2-oxocarboxylate (II) to the (S)-2-hydroxycarboxylate (III) is new. Independent claims are also included for: (1) fragment (F) of an oxidoreductase containing 5-30 amino acids (aa) from a 294 aa sequence (18), reproduced; (2) fusion protein (FP) comprising sequence (18), or (F), fused at either end to an additional peptide; (3) antibody (Ab) specific for sequence (18) or its fragments of 15 or 12 aa (sequences (1) and (2), respectively); (4) isolated nucleic acid (NA) that encodes (1), (2), (18) or (I) generally; (5) cloning or expression vector that contains NA; (6) host cells transformed or transfected with the vector of (5); and (7) enantioselective preparation of (III) by reducing (II) in presence of (I) and NADPH. |
