CC   -!- FUNCTION: Part of the mycobacterial fatty acid elongation system FAS-
CC       II, which is involved in mycolic acid biosynthesis. Catalyzes the
CC       elongation of long chain acyl-ACP substrates by the addition of two
CC       carbons from malonyl-ACP to an acyl acceptor. Involved in the initial
CC       extension of the mycolate chain and forms monounsaturated fatty acids
CC       that averaged 40 carbons in length. {ECO:0000250|UniProtKB:P9WQD9}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an ultra-long-chain mono-unsaturated fatty acyl-[ACP] + H(+) +
CC         malonyl-[ACP] = a 3-oxo-ultra-long-chain mono-unsaturated fatty acyl-
CC         [ACP] + CO2 + holo-[ACP]; Xref=Rhea:RHEA:65312, Rhea:RHEA-COMP:9623,

CC   -!- PATHWAY: Lipid metabolism; mycolic acid biosynthesis.
CC       {ECO:0000250|UniProtKB:P9WQD9}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P9WQD9}.
CC   -!- INDUCTION: Repressed by Rip1 and independently by the metal chelator
CC       phenanthroline. {ECO:0000269|PubMed:20545848}.
CC   -!- SIMILARITY: Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP
CC       synthases family. {ECO:0000305}.
