EC Tree
IUBMB Comments
The enzyme, found in both eukaryotes and prokaryotes, catalyses the Claisen condensation of an acetyl-CoA and an acyl-CoA (often another acetyl-CoA), leading to the formation of an acyl-CoA that is longer by two carbon atoms. The reaction starts with the acylation of a nucleophilic cysteine at the active site, usually by acetyl-CoA but potentially by a different acyl-CoA, with concomitant release of CoA. In the second step the acyl group is transferred to an acetyl-CoA molecule. cf. EC 2.3.1.16, acetyl-CoA C-acyltransferase.
