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.
