ID   2.3.1.294
DE   meromycolic acid 3-oxoacyl-(acyl carrier protein) synthase II.
AN   beta-ketoacyl-acyl carrier protein synthase KasB.
CA   an ultra-long-chain di-unsaturated fatty acyl-[ACP] + H(+) + malonyl-
CA   [ACP] = a 3-oxo-ultra-long-chain di-unsaturated fatty acyl-[ACP] + CO2 +
CA   holo-[ACP].
CC   -!- The enzyme is part of the fatty acid synthase (FAS) II system of
CC       mycobacteria, which extends modified products of the FAS I system,
CC       eventually forming meromycolic acids that are incorporated into
CC       mycolic acids.
CC   -!- Meromycolic acids consist of a long chain, typically 50-60 carbons,
CC       which is functionalized by different groups.Two 3-oxoacyl-(acyl
CC       carrier protein) synthases function within the FAS II system, encoded
CC       by the kasA and kasB genes.
CC   -!- The two enzymes share some sequence identity but function
CC       independently on separate sets of substrates.
CC   -!- KasB differs from KasA (EC 2.3.1.293), by preferring longer
CC       substrates (closer to the upper limit), which also contain two double
CC       bonds.
