CC -!- FUNCTION: Involved in the type II fatty acid elongation cycle.
CC Catalyzes the elongation of a wide range of acyl-ACP by the addition of
CC two carbons from malonyl-ACP to an acyl acceptor. Can efficiently
CC catalyze the conversion of palmitoleoyl-ACP (cis-hexadec-9-enoyl-ACP)
CC to cis-vaccenoyl-ACP (cis-octadec-11-enoyl-ACP), an essential step in
CC the thermal regulation of fatty acid composition.
CC {ECO:0000256|PIRNR:PIRNR000447}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(9Z)-hexadecenoyl-[ACP] + H(+) + malonyl-[ACP] = 3-oxo-(11Z)-
CC octadecenoyl-[ACP] + CO2 + holo-[ACP]; Xref=Rhea:RHEA:55040,

CC Evidence={ECO:0000256|PIRNR:PIRNR000447};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a fatty acyl-[ACP] + H(+) + malonyl-[ACP] = a 3-oxoacyl-[ACP]
CC + CO2 + holo-[ACP]; Xref=Rhea:RHEA:22836, Rhea:RHEA-COMP:9623,

CC Evidence={ECO:0000256|PIRNR:PIRNR000447};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC {ECO:0000256|ARBA:ARBA00005194, ECO:0000256|PIRNR:PIRNR000447}.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP
CC synthases family. {ECO:0000256|ARBA:ARBA00008467,
CC ECO:0000256|PIRNR:PIRNR000447, ECO:0000256|RuleBase:RU003694}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
