IntEnz Enzyme Nomenclature
EC 2.3.1.86

Names

Accepted name:
fatty-acyl-CoA synthase
Other names:
yeast fatty acid synthase
FAS1 (gene name)
FAS2 (gene name)
Systematic name:
acyl-CoA:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl- and enoyl- reducing)

Reaction

Comments:

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, 3-oxoacyl-[acyl-carrier-protein] synthase, 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-hydroxypalmitoyl-[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 differs from the animal enzyme (EC 2.3.1.85) 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.
