Protein

3-oxoacyl-[acyl-carrier-protein] synthase 3 protein 2

Gene

fabH2

Organism
Bacillus cereus (strain ATCC 14579 / DSM 31)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Catalyzes the first condensation reaction which initiates fatty acid synthesis and may therefore play a role in governing the total rate of fatty acid production. Possesses both acetoacetyl-ACP synthase and acetyl transacylase activities. Its substrate specificity determines the biosynthesis of branched-chain and/or straight-chain of fatty acids.UniRule annotation

Catalytic activityi

Acetyl-CoA + malonyl-[acyl-carrier-protein] = acetoacetyl-[acyl-carrier-protein] + CoA + CO2.UniRule annotation
