Application

Acetoacetyl coenzyme A (Acetoacetyl-CoA) may be used as a substrate for a number of enzymes including; acetoacetyl-CoA thiolase (EC 2.3.1) which produces acetyl-CoA in reverse condensation reaction and (3-Hydroxy-3-methylglutaryl coenzyme A (CoA) synthase (HMGCS)) which produces 3-hydroxy-3-methylglutaryl (HMG)-CoA in the mevalonate pathway leading to terpenoid biosynthesis. Acetoacetyl-CoA is also a precursor of poly-beta-hydroxybutyrate polymers in microorganisms.
Substrate for acetoacetyl-CoA thiolase EC 2.3.1.9; Role in the biosynthesis of nonactin.

The formation of carbon-carbon bonds via an acyl-enzyme intermediate plays a central role in fatty acid, polyketide, and isoprenoid biosynthesis. Uniquely among condensing enzymes, 3-hydroxy-3-methylglutaryl (HMG)-CoA synthase (HMGS) catalyzes the formation of a carbon-carbon bond by activating the methyl group
