Reaction(KEGG)
Substrate
acetyl-CoA [CPD:C00024];
[acyl-carrier protein] [CPD:C00229]

Comment
This enzyme, along with EC 2.3.1.39, [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 beta-ketoacyl-ACP synthase III (EC 2.3.1.180) [5].
