Protein

Fatty acid synthase subunit alpha

Gene

FAS2

Organism
Candida albicans (Yeast)
Status
Reviewed - Annotation score: 5 out of 5- Protein inferred from homologyi

Functioni

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 activityi

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