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.

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

[Alpha6beta6] hexamers of two multifunctional subunits (alpha and beta).

Sequence similarities

Belongs to the fungal fatty acid synthetase subunit alpha family.

Contains 1 acyl carrier domain.
