IntEnz Enzyme Nomenclature


Accepted name:
[acyl-carrier-protein] S-acetyltransferase
Other names:
[acyl-carrier protein]-acetyltransferase
acetyl coenzyme A-acyl-carrier-protein transacylase
ACP acetyltransferase
acyl-carrier-protein acetyltransferase
Systematic name:
acetyl-CoA:[acyl-carrier-protein] S-acetyltransferase



This enzyme, along with EC, [acyl-carrier-protein] S-malonyltransferase, is essential for the initiation of fatty-acid biosynthesis in bacteria. The substrate acetyl-CoA protects the enzyme against inhibition by N-ethylmaleimide or iodoacetamide [4]. This is one of the activities associated with β-ketoacyl-ACP synthase III (EC [5].
