ENZYME entry: EC 1.1.1.383

Accepted Name
ketol-acid reductoisomerase [NAD(P)(+)]
Reaction catalysed
  • (2R)-2,3-dihydroxy-3-methylbutanoate + NAD(+) <=> (2S)-2-acetolactate + H(+) + NADH
  • (2R)-2,3-dihydroxy-3-methylbutanoate + NADP(+) <=> (2S)-2-acetolactate + H(+) + NADPH
Comment(s)
The enzyme, characterized from the bacteria Hydrogenobaculum sp. and Syntrophomonas wolfei subsp. wolfei and from the archaea Metallosphaera sedula and Ignisphaera aggregans, can use both NADH and NADPH with similar efficiency (cf. EC 1.1.1.86 and EC 1.1.1.382).
