CC -!- FUNCTION: Catalyzes the elongation by iterative transfer of p-
CC hydroxybenzoyl group from FadD22 (pHBA-S-FAdD22) to form p-
CC hydroxyphenylalkanoate (pHPA) intermediates during phenolphthiocerol
CC (PPOL) biosynthesis. PPOL is an important intermediate in the
CC biosynthesis of phenolic glycolipid (mycosid B).
CC {ECO:0000269|PubMed:19799378}.
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 EC=2.3.1.41; Evidence={ECO:0000255|PROSITE-ProRule:PRU10022};
CC -!- COFACTOR:
CC Name=pantetheine 4'-phosphate; Xref=ChEBI:CHEBI:47942;
CC Evidence={ECO:0000250};
CC Note=Binds 1 phosphopantetheine covalently. {ECO:0000250};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP
CC synthases family. {ECO:0000305}.
