Unknown protein; Sugar octanoyltransferase likely involved in the biosynthesis of mycobacterial methylglucose lipopolysaccharide (MGLP). Catalyzes the transfer of an octanoyl group from octanoyl-CoA to the C6 OH of the second glucose in diglucosylglycerate (DGG). DGG is the preferred acceptor, but to a lesser extent, GG (glucosylglycerate) can also be used as substrate. DGG and GG are the two earliest intermediates in MGLP biosynthesis.

Possible lipase LipV; Lipase that displays broad substrate specificity and preferentially hydrolyzes p-nitrophenyl myristate in vitro. Also shows significant activity with pNP-butyrate (68%), pNP-octanoate (82%), pNP- decanoate (90%), and pNP-laurate (74%). Is probably involved in lipid catabolism. Is active at low pH, and might play some important role in mycobacterial biology in macrophages where the bacteria encounters acidic stress.

A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Probable polyketide synthase Pks5; Polyketide synthase likely involved in the biosynthesis of a polymethyl-branched fatty acid (PMB-FA) that might only be produced during host infection. Is required for the full virulence of M.tuberculosis during host infection.

Polyketide synthase Pks12; Rv2048c, (MTV018.35c), len: 4151 aa. Pks12,polyketide synthase similar to many. Contains 2x PS00012 Phosphopantetheine attachment site, 2x PS00606 Beta-ketoacyl synthases active site, and PS00343 Gram-positive cocci surface proteins 'anchoring' hexapeptide. Nucleotide position 2297976 in the genome sequence has been corrected, G:A resulting in S3004L.

Phenolpthiocerol synthesis type-I polyketide synthase PpsC; Involved in the elongation of either C22-24 fatty acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol derivatives.
