3-Hydroxy-3-methylglutaryl-CoA lyase (or HMG-CoA lyase) is an enzyme (EC 4.1.3.4 that in human is encoded by the HMGCL gene located on chromosome 1. It is a key enzyme in ketogenesis (ketone body formation). It is a ketogenic enzyme in the liver that catalyzes the formation of acetoacetate from HMG-CoA within the mitochondria. It also plays a prominent role in the catabolism of the amino acid leucine.
