Identification
Name: (2R,3S)-3-isopropylmalate
Description:3-Isopropylmalate is an intermediate in valine, leucine and isoleucine biosynthesis. It is a substrate for 3-isopropylmalate dehydrogenase (TT_C0867) and can be generated from the reduction of 2-isopropyl-3-oxosuccinate. Leucine biosynthesis involves a five-step conversion process starting with the valine precursor 2-keto-isovalerate. The final step in this pathway is catalyzed by two transaminases of broad specificity, Branched-chain amino acid transferase (IlvE) and Tyrosine aminotransferase (TyrB). This pathway is part of the superpathway of leucine, valine, and isoleucine biosynthesis, that generates not only isoleucine and valine, but also leucine.
