Possible lipoprotein LppD; Rv1899c, (MTCY180.19), len: 343 aa. Possible lipoprotein; contains appropriately localized lipoprotein lipid attachment site (PS00013). Some similarity to C-terminal part of AE000717|AE000717_4 hypothetical protein from Aquifex aeolicus section 49 (165 aa), FASTA results: opt: 372, E(): 2.3e-14, (43.5% identity in 147 aa overlap); and Q44020 4-hydroxybutyrate dehydrogenase (173 aa), FASTA results: opt: 272, E(): 4.7e-09, (35.8% identity in 165 aa overlap).

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.

Deamidase of pup Dop; Specifically catalyzes the deamidation of the C-terminal glutamine of the prokaryotic ubiquitin-like protein Pup to glutamate, thereby rendering Pup competent for conjugation. Also displays depupylase (DPUP) activity, removing conjugated Pup from target proteins; is thus involved in the recycling of Pup and may function similarly to deubiquitinases (DUBs) in eukaryotes to prevent or promote proteasomal degradation of certain proteins. Belongs to the Pup ligase/Pup deamidase family. Pup deamidase subfamily.

Rv0337c, (MTCY279.04c), len: 429 aa. Probable aspC,aspartate aminotransferase (transaminase A), equivalent to CAC32019.1|AL583925 probable aspartate aminotransferase from Mycobacterium leprae (437 aa). Also highly similar to many e.g. Q48143|U32823 aspartate aminotransferase (404 aa), FASTA scores: opt: 1646, E(): 0, (57.2% identity in 404 aa overlap). Also some similarity to Rv3565|MTCY06G11.12 from Mycobacterium tuberculosis FASTA score: (27.2% identity in 383 aa overlap). Belongs to class-I of pyridoxal-phosphate-dependent aminotransferases. Cofactor: pyridoxal phosphate.

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.

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.

Rv2940c, (MTCY24G1.09, MTCY19H9.08c), len: 2111 aa. Probable mas, mycocerosic acid synthase membrane associated, multifunctional enzyme (see citations below),almost identical to Q02251|MCAS_MYCBO|mas mycocerosic acid synthase from Mycobacterium bovis (2110 aa), FASTA scores: opt: 13226, E(): 0, (95.8% identity in 2115 aa overlap) (see Mathur & Kolattukudy 1992); and equivalent to Q9CD78|mas|ML0139 putative mycocerosic synthase from Mycobacterium leprae (2116 aa), FASTA scores: opt: 12142,E(): 0, (87.95% identity in 2119 aa overlap); and Q49624|PKS3|MASA|ML1229|B1170_C2_209 probable myc [...]

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.
