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

Acetyl-CoA + malonyl-[acyl-carrier-protein] = acetoacetyl-[acyl-carrier-protein] + CoA + CO2. HAMAP MF_01815

Pathway

Lipid metabolism; fatty acid biosynthesis. HAMAP MF_01815 SAAS SAAS013747

Subunit structure

Homodimer By similarity. HAMAP MF_01815 SAAS SAAS013747

Subcellular location

Cytoplasm By similarity HAMAP MF_01815 SAAS SAAS013747.

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. HAMAP MF_01815
