Ketol-acid reductoisomerase (NADP(+)).
based on mapping to UniProt P9WKJ7
(1) (2R)-2,3-dihydroxy-3-methylbutanoate + NADP(+) = (2S)-2-hydroxy-2- methyl-3-oxobutanoate + NADPH. (2) (2R,3R)-2,3-dihydroxy-3-methylpentanoate + NADP(+) = (S)-2-hydroxy-2- ethyl-3-oxobutanoate + NADPH.
-!- The enzyme, found in many bacteria and archaea, is specific for NADPH (cf. EC 1.1.1.382 and EC 1.1.1.383). -!- Formerly EC 1.1.1.89.
