Fatty-acid-CoA ligase FadD19 (fatty-acid-CoA synthetase) (fatty-acid-CoA synthase); Catalyzes the activation of long-chain fatty acids as acyl- coenzyme A (acyl-CoA), which are then transferred to the multifunctional polyketide synthase (PKS) type III for further chain extension. Also involved in the degradation of cholesterol via the degradation of the side chains of C-24 branched-chain sterols. Catalyzes the ATP-dependent CoA thioesterification of the sterol 3- oxocholest-4-en-26-oate to yield 3-oxocholest-4-en-26-oyl-CoA. It can also use 3beta-hydroxy-5-cholesten-26-oate.

Probable fatty-acid-CoA ligase FadD18 (Fatty-acid-CoA synthetase) (Fatty-acid-CoA synthase); Rv3513c, (MTV023.20c), len: 218 aa (Start uncertain). Probable fadD18, fatty-acid-CoA synthetase (C-terminal fragment), almost identical to C-terminal end of downstream O53560|FADD19|Rv3515c|MTV023.22c, probably result of partial gene duplication. Also similar at the C-terminus to other fatty-acid-CoA synthetases e.g. Q9EXL2|FADD from Streptomyces griseus (540 aa), FASTA scores: opt: 586, E(): 1.2e-28, (52.45% identity in 185 aa overlap); AAB87139|MIG medium chain acyl-CoA synthetase precursor [...]

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.

Polyketide synthase Pks2; Catalyzes the synthesis of the hepta- and octamethyl phthioceranic acids and/or hydroxyphthioceranic acids that are the major acyl constituents of sulfolipids.

50S ribosomal protein L6 RplF; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.
