Myristoyl-CoA is a 14-carbon fatty acyl-CoA derivative formed by the covalent attachment of myristate to coenzyme A in a reaction catalyzed by myristoyl-CoA synthetase. Myristoyl-CoA serves as the primary donor molecule for myristoylation, a post-translational modification in which the myristoyl group is covalently attached to the lysine or N-terminal glycine residue of a target protein. Whereas myristoyl-CoA synthesis is catalyzed by myristoyl-CoA synthetase, protein myristoylation is catalyzed by N-myristoyltransferases (NMTs). Myristoyl-CoA also acts as an intermediate in the β-oxidation of fatty acids, and in other lipid synthesis pathways.
