Comment
The animal enzyme is a multi-functional protein catalysing the reactions of EC 2.3.1.38 [acyl-carrier-protein] S-acetyltransferase, EC 2.3.1.39 [acyl-carrier-protein] S-malonyltransferase, EC 2.3.1.41 β-ketoacyl-[acyl-carrier-protein] synthase I, EC 1.1.1.100 3-oxoacyl-[acyl-carrier-protein] reductase, EC 4.2.1.59 3-hydroxyacyl-[acyl-carrier-protein] dehydratase, EC 1.3.1.39 enoyl-[acyl-carrier-protein] reductase (NADPH, Re-specific) and EC 3.1.2.14 oleoyl-[acyl-carrier-protein] hydrolase. cf. EC 2.3.1.86, fatty-acyl-CoA synthase system.
