Protein

Fatty acid synthase subunit beta

Gene

FAS1

Organism
Yarrowia lipolytica (strain CLIB 122 / E 150) (Yeast) (Candida lipolytica)
Status
Reviewed-Annotation score: 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 beta subunit contains domains for: [acyl-carrier-protein] acetyltransferase and malonyltransferase, S-acyl fatty acid synthase thioesterase, enoyl-[acyl-carrier-protein] reductase, and 3-hydroxypalmitoyl-[acyl-carrier-protein] dehydratase.

Catalytic activityi

Acetyl-CoA + n malonyl-CoA + 2n NADPH = long-chain-acyl-CoA + n CoA + n CO2 + 2n NADP+.
Acetyl-CoA + [acyl-carrier-protein] = CoA + acetyl-[acyl-carrier-protein].
Malonyl-CoA + an [acyl-carrier-protein] = CoA + a malonyl-[acyl-carrier-protein].
A (3R)-3-hydroxyacyl-[acyl-carrier protein] = a trans-2-enoyl-[acyl-carrier protein] + H2O.
An acyl-[acyl-carrier protein] + NAD+ = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADH.
Oleoyl-[acyl-carrier-protein] + H2O = [acyl-carrier-protein] + oleate.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
