Reactions
NADPH + H+ + 2-Acetolactate = NADP+ + 2,3-Dihydroxy-3-methylbutanoate
NADP+ + (R)-2,3-Dihydroxy-3-methylbutanoate = NADPH + H+ + (S)-2-Acetolactate
NADP+ + (R)-2,3-Dihydroxy-3-methylbutanoate = NADPH + H+ + 3-Hydroxy-3-methyl-2-oxobutanoic acid
NADP+ + (R)-2,3-Dihydroxy-3-methylpentanoate = NADPH + H+ + (R)-3-Hydroxy-3-methyl-2-oxopentanoate
(S)-2-Aceto-2-hydroxybutanoate = (R)-3-Hydroxy-3-methyl-2-oxopentanoate
(S)-2-Acetolactate = 3-Hydroxy-3-methyl-2-oxobutanoic acid
