Rv0954, (MTCY10D7.20c), len: 303 aa. Probable conserved transmembrane protein, highly similar to 34KD_MYCPA|Q04959 34 kDa antigenic protein from Mycobacterium paratuberculosis (298 aa), FASTA scores: opt: 1023, E(): 7.2e-36, (59.3% identity in 305 aa overlap); AAC69251.1|U82111 34 kDa antigen precursor from Mycobacterium leprae (336 aa); and AL035500|MLCL373.06 hypothetical membrane protein from Mycobacterium leprae (297 aa), FASTA score: (55.6% identity in 315 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Rv3604c, (MTCY07H7B.18), len: 397 aa. Probable conserved ala-, arg-, pro-rich transmembrane protein,equivalent to O69526|MLCB2548.03c|ML0228 putative membrane protein from Mycobacterium leprae (432 aa), FASTA scores: opt: 869, E(): 2.9e-31, (59.7% identity in 432 aa overlap). Contains two possible membrane-spanning domains. N-terminus shortened since first submission (previously 462 aa). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Lysine-N-oxygenase MbtG (L-lysine 6-monooxygenase) (lysine N6-hydroxylase); Flavoprotein monooxygenase required for N-hydroxylation of the two acylated lysine residues during mycobactin assembly, thus producing the hydroxamate groups necessary for iron sequestration. Is also able, but less efficiently, to hydroxylate L-lysine (non acylated) in vitro.

Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate; Belongs to the GART family.

Phosphoribosylaminoimidazolecarboxamide formyltransferase; Rv0957, (MTCY10D7.17c), len: 523 aa. Probable purH,bifunctional purine biosynthesis protein including 5'-phosphoribosyl-5-aminoimidazole-4-carboxamide formyltransferase and inosine-monophosphate (imp) cyclohydrolase, equivalent to AL035500|MLCL373_8 putative phosphoribosylaminoimidazolecarboxamide formyltransferase from Mycobacterium leprae (527 aa), FASTA score: (88.1% identity in 520 aa overlap); and AF05727.1|AF191543_2|AF191543|PurH from Mycobacterium avium subsp. paratuberculosis (527 aa). Also highly similar to others e.g [...]

Possible arabinofuranosyltransferase AftD; Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall. Catalyzes the addition of an arabinofuranosyl (Araf) residue from the sugar donor decaprenyl-phospho-arabinose (DPA) on the C-3 of an alpha-(1->5)-linked Araf from the arabinan backbone of AG.

Mannosyltransferase PimE; Catalyzes the alpha-1,2 addition of a mannose residue from polyprenol-phosphate-mannose (PPM) to a monoacyl phosphatidylinositol pentamannoside (AcPIM5) to generate a monoacyl phosphatidylinositol hexamannoside (AcPIM6).

Hypothetical alanine rich protein; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigM. ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P, Rip1), while cytoplasmic proteases finish degr [...]

Rv0256c, (MTV034.22c), len: 556 aa. PPE2, Member of the M. tuberculosis PPE family, similar to many e.g. Rv0280, Rv0286, etc. Equivalent to Z98756|MLCB2492.30 from Mycobacterium leprae (572 aa), FASTA scores: opt: 1837,E(): 0, (62.9% identity in 461 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
