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,
