Class a beta-lactamase BlaC; Extended spectrum beta-lactamase (ESBL) that inactivates beta-lactam antibiotics by hydrolyzing the amide group of the beta- lactam ring. Displays high levels of penicillinase and cephalosporinase activity as well as measurable activity with carbapenems, including imipenem and meropenem. Plays a primary role in the intrinsic resistance of M.tuberculosis to beta-lactam antibiotics.

Rv3160c, (MTV014.04c), len: 213 aa. Possible transcriptional regulator, with some similarity to others e.g. Q9S3L4|AMTR AMTR protein (global repressor in the nitrogen regulation system; see Jakoby et al., 2000) (222 aa), FASTA scores: opt: 182, E(): 7.3e-05, (27.9% identity in 208 aa overlap); Q9X7X9|SC6A5.33c putative regulatory protein from Streptomyces coelicolor (223 aa), FASTA scores: opt: 176, E(): 0.00018, (26.5% identity in 185 aa overlap); Q9XA31|SCH69.03c putative transcriptional regulator from Streptomyces coelicolor (209 aa), FASTA scores: opt: 173, E(): 0.00027, (27.25% id [...]

Glucosyl-3-phosphoglycerate phosphatase GpgP; Involved in the biosynthesis of mycobacterial methylglucose lipopolysaccharides (MGLPs). Catalyzes the dephosphorylation of glucosyl-3-phosphoglycerate (GPG) to glucosylglycerate (GG). GPG is the preferred substrate, but GpgP also exhibits low dephosphorylation activity on mannosyl-3-phosphoglycerate (MPG) and mannosylglucosyl-3- phosphoglycerate (MGPG) in vitro. Shows only trace of phosphoglycerate mutase (PGM) activity.

Probable galactokinase GalK (galactose kinase); Catalyzes the transfer of the gamma-phosphate of ATP to D- galactose to form alpha-D-galactose-1-phosphate (Gal-1-P).

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.

Conserved hypothetical protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation. Belongs to the Iojap/RsfS family.

Rv0449c, (MTV037.13c), len: 439 aa. Conserved hypothetical protein, some similarity with several hypothetical proteins and various enzymes e.g. AAK24569.1|AE005927 amine oxidase, flavin-containing from Caulobacter crescentus (454 aa); BAB02771.1|AB023036 mycolic acid methyl transferase-like protein from Arabidopsis thaliana (842 aa); BAB01742.1|AP000374 protein which contains similarity to cyclopropane fatty acid synthase from Arabidopsis thaliana (793 aa); etc. Has hydrophobic stretch at N-terminus.

Hypothetical protein; Rv2423, (MTCY428.24c), len: 348 aa. Hypothetical unknown protein.

Probable preprotein translocase SecA1 1 subunit; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of precursor proteins, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane (By similarity).
