'''3-Isopropylmalate dehydrogenase''' (IMDH) catalyzes the oxidative decarboxylation of 3-isopropylmalate (3IPM) to 2-oxo-4-methylvalerate. This reaction is a step in the biosynthesis of leucine in bacteria and fungi. IMDH uses [[NAD]] as a cofactor. IMDH is a bifunctional enzyme that catalyzes dehydrogenation and decarboxylation in the presence of NAD and a divalent cation<ref>PMID:17979826</ref>. | '''3-Isopropylmalate dehydrogenase''' (IMDH) catalyzes the oxidative decarboxylation of 3-isopropylmalate (3IPM) to 2-oxo-4-methylvalerate.
