Protein
3-oxoacyl-[acyl-carrier-protein] synthase 3 protein 1
Organism
Bacillus subtilis (strain 168)
Function
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. Has some substrate specificity for branched chain acyl-CoA, determining the biosynthesis of branched-chain of fatty acids instead of straight-chain.
Similarity
Belongs to the thiolase-like superfamily. FabH family.
