Probable arabinosyltransferase A; Arabinosyl transferase responsible for the polymerization of arabinose into the arabinan of arabinogalactan.

Arabinofuranosyltransferase AftA; 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 the first key arabinofuranosyl (Araf) residue from the sugar donor decaprenyl-phospho-arabinose (DPA) on the C-5 of a 6-linked galactofuranosyl (Galf) of the galactan domain, thus 'priming' the galactan for further elaboration by other arabinofuranosyltransferases. It is not able to add an Araf residue to a terminal Galf. Belongs to the glycosyltransf [...]

NADH-dependent enoyl-[acyl-carrier-protein] reductase InhA (NADH-dependent enoyl-ACP reductase); Enoyl-ACP reductase of the type II fatty acid syntase (FAS- II) system, which is involved in the biosynthesis of mycolic acids, a major component of mycobacterial cell walls. Catalyzes the NADH-dependent reduction of the double bond of 2-trans- enoyl-[acyl-carrier protein], an essential step in the fatty acid elongation cycle of the FAS-II pathway. Shows preference for long-chain fatty acyl thioester substrates (>C16), and can also use 2-trans-enoyl-CoAs as alternative substrates. The mycob [...]

DNA gyrase subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable con [...]

DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

30S ribosomal protein S12 RpsL; With S4 and S5 plays an important role in translational accuracy.

Pyrazinamidase/nicotinamidase PncA (PZase); Catalyzes the deamidation of nicotinamide (NAM) into nicotinate. Likely functions in the cyclical salvage pathway for production of NAD from nicotinamide (By similarity). Belongs to the isochorismatase family.

Catalase-peroxidase-peroxynitritase T KatG; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity, oxidizing various electron donors including NADP(H). Protects M.tuberculosis against toxic reactive oxygen species (ROS) including hydrogen peroxide as well as organic peroxides and thus contributes to its survival within host macrophages by countering the phagocyte oxidative burst. Also displays efficient peroxynitritase activity, which may help the bacterium to persist in macrophages. Catalyzes the oxidative activation of the antitubercular pro- drug isoniazid (I [...]

DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. . Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable c [...]
