Protein existence	Inferred from homology

General annotation (Comments)

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. Its substrate specificity determines the biosynthesis of branched-chain and/or straight-chain of fatty acids By similarity. HAMAP MF_01815
Catalytic activity	Acyl-[acyl-carrier-protein] + malonyl-[acyl-carrier-protein] = 3-oxoacyl-[acyl-carrier-protein] + CO2 + [acyl-carrier-protein]. HAMAP MF_01815
Pathway	Lipid metabolism; fatty acid biosynthesis. HAMAP MF_01815
Subunit structure	Homodimer By similarity. HAMAP MF_01815
Subcellular location	Cytoplasm Probable HAMAP MF_01815.
Domain	The last Arg residue of the ACP-binding site is essential for the weak association between ACP/AcpP and FabH By similarity. HAMAP MF_01815
Sequence similarities	Belongs to the FabH family.
