Identification
Name:2,3-Dihydroxyisovaleric acid
Description2,3-dihydroxyisovaleric acid (or 2,3-Dihydroxy-3-methylbutanoate) is invovled in branched chain amino acid biosynthesis. It is a substrate for Ketol-acid reductoisomerase (ilvC). This enzyme catalyzes the reaction: (R)-2,3-dihydroxy-3-methylbutanoate + NADP+ = (S)-2-hydroxy-2-methyl-3-oxobutanoate + NADPH.
