General annotation (Comments)

Function

Fatty acid synthetase catalyzes the formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH. The alpha subunit contains domains for: acyl carrier protein, 3-oxoacyl-[acyl-carrier-protein] reductase, and 3-oxoacyl-[acyl-carrier-protein] synthase By similarity.

Catalytic activity

Acetyl-CoA + n malonyl-CoA + 2n NADH + 2n NADPH = long-chain-acyl-CoA + n CoA + n CO2 + 2n NAD+ + 2n NADP+.

Acyl-[acyl-carrier-protein] + malonyl-[acyl-carrier-protein] = 3-oxoacyl-[acyl-carrier-protein] + CO2 + [acyl-carrier-protein].

(3R)-3-hydroxyacyl-[acyl-carrier-protein] + NADP+ = 3-oxoacyl-[acyl-carrier-protein] + NADPH.

Subunit structure

Fatty acid synthase is composed of alpha and beta subunits By similarity.

Induction

Induced by oleic acid and stearic acid, but not by linoleic acid. Ref.3

Sequence similarities

Belongs to the fungal fatty acid synthetase subunit alpha family.

Contains 1 acyl carrier domain.
