CC -!- FUNCTION: Catalyzes the condensation reaction of fatty acid synthesis
CC by the addition to an acyl acceptor of two carbons from malonyl-ACP.
CC Catalyzes the first condensation reaction which initiates fatty acid
CC synthesis and may therefore play a role in governing the total rate of
CC fatty acid production. Possesses both acetoacetyl-ACP synthase and
CC acetyl transacylase activities. Its substrate specificity determines
CC the biosynthesis of branched-chain and/or straight-chain of fatty
CC acids. {ECO:0000256|HAMAP-Rule:MF_01815}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + H(+) + malonyl-[ACP] = 3-oxobutanoyl-[ACP] + CO2
CC + CoA; Xref=Rhea:RHEA:12080, Rhea:RHEA-COMP:9623, Rhea:RHEA-

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:12081;
CC Evidence={ECO:0000256|ARBA:ARBA00043707};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC {ECO:0000256|ARBA:ARBA00005194, ECO:0000256|HAMAP-Rule:MF_01815}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01815}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01815}.
CC -!- DOMAIN: The last Arg residue of the ACP-binding site is essential for
CC the weak association between ACP/AcpP and FabH. {ECO:0000256|HAMAP-
CC Rule:MF_01815}.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. FabH family.
CC {ECO:0000256|ARBA:ARBA00008642, ECO:0000256|HAMAP-Rule:MF_01815}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
