Comment
The enzyme from yeasts (Ascomycota and Basidiomycota) is a multi-functional protein complex composed of two subunits. One subunit catalyses the reactions EC 1.1.1.100, 3-oxoacyl-[acyl-carrier-protein] reductase and EC 2.3.1.41, beta-ketoacyl-[acyl-carrier-protein] synthase I, while the other subunit catalyses the reactions of EC 2.3.1.38, [acyl-carrier-protein] S-acetyltransferase, EC 2.3.1.39, [acyl-carrier-protein] S-malonyltransferase, EC 4.2.1.59, 3-hydroxyacyl-[acyl-carrier-protein] dehydratase, EC 1.3.1.10, enoyl-[acyl-carrier-protein] reductase (NADPH, Si-specific) and EC 1.1.1.279, (R)-3-hydroxyacid-ester dehydrogenase. The enzyme system differs from the animal system (EC 2.3.1.85, fatty-acid synthase system) in that the enoyl reductase domain requires FMN as a cofactor, and the ultimate product is an acyl-CoA (usually palmitoyl-CoA) instead of a free fatty acid.
