Your Input:
thrSProbable threonyl-tRNA synthetase ThrS (threonine-tRNA synthetase)(ThrRS) (threonine-tRNA ligase); Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged L-seryl-tRNA(Thr). (692 aa)
pstPPhosphoserine/threonine phosphatase PstP; The only predicted protein phosphatase in M.tuberculosis, it dephosphorylates at least 5 protein kinases (PknA, PknB, PknD, PknE and PknF) and the penicillin-binding protein PBPA. (514 aa)
vapC1Possible toxin VapC1; Toxic component of a type II toxin-antitoxin (TA) system. The cognate antitoxin is VapB1 (By similarity). Has ribonuclease activity. (133 aa)
PE_PGRS3PE-PGRS family protein PE_PGRS3; Rv0278c, (MTV035.06c), len: 957 aa. PE_PGRS3, Member of the Mycobacterium tuberculosis PE family (see citation below), PGRS subfamily of gly-rich proteins, similar to many e.g. Z95890|MTCY28_25|Rv1759c from Mycobacterium tuberculosis (914 aa), FASTA scores: opt: 3849, E(): 0,(67.8% identity in 903 aa overlap). Contains PS00583 pfkB family of carbohydrate kinases signature 1. (957 aa)
esxHLow molecular weight protein antigen 7 EsxH (10 kDa antigen) (CFP-7) (protein TB10.4); EsxH, in complex with EsxG, disrupts ESCRT function and impairs host phagosome maturation, thereby promoting intracellular bacterial growth. The complex acts by interacting, via EsxH, with the host hepatocyte growth factor-regulated tyrosine kinase substrate (HGS/HRS), a component of the ESCRT machinery. Belongs to the WXG100 family. ESAT-6 subfamily. (96 aa)
vapC2Possible toxin VapC2; Toxic component of a type II toxin-antitoxin (TA) system. Acts as an RNase. Upon expression in M.smegmatis inhibits translation, growth and colony formation. All its toxic effects are neutralized by coexpression with cognate antitoxin VapB2. (141 aa)
groEL260 kDa chaperonin 2; Prevents aggregation of substrate proteins and promotes their refolding. (540 aa)
vapC29Possible toxin VapC29. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. Its cognate antitoxin is VapB29 (By similarity). Has ribonuclease activity. (133 aa)
vapC5Possible toxin VapC5; Probable toxic component of a type II toxin-antitoxin (TA) system. The cognate antitoxin is VapB5. Has limited RNase activity on substrates; activity is seen with a VapC5-VapB5 complex. (135 aa)
mazF3Toxin MazF3; Toxic component of a type II toxin-antitoxin (TA) system. Acts as an mRNA and 23S rRNA interferase, cleaving predominantly after the first 2 Us in the sequence 5'-UUCCU-3'; in 23S rRNA only cleaves once in the ribosomal A site in dissociated but not intact ribosomes. Cleavage of 23S rRNA inhibits protein translation; the 23S rRNA region cleaved is involved in tRNA-binding in the A site, 30S and 50S subunit interaction and ribosome recycling factor association. Upon expression in E.coli and M.smegmatis inhibits cell growth and colony formation. It dramatically increases per [...] (103 aa)
Rv1366Hypothetical protein; Rv1366, (MTCY02B10.30), len: 273 aa. Hypothetical unknown protein. (273 aa)
gmkProbable guanylate kinase Gmk; Essential for recycling GMP and indirectly, cGMP. (208 aa)
vapC11Possible toxin VapC11; Toxic component of a type II toxin-antitoxin (TA) system. Acts as an RNase. Upon expression in E.coli and M.smegmatis inhibits translation, cell growth and colony formation. Its toxic effects on cell growth and colony formation are neutralized by coexpression with cognate antitoxin VapB11; the effect on translation has not been tested but is probably also neutralized. (134 aa)
higBPossible toxin HigB; Toxic component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis inhibits colony formation and cell growth. Ectopic expression in wild-type M.tuberculosis has no effect on cell growth; ectopic expression in a triple higB1-higA1-Rv1957 (delta TAC) disruption mutant causes growth arrest, killing a considerable proportion of the cells. Increased ectopic expression leads to decreased levels of IdeR- and Zur-regulated genes as well as cleavage within the mRNA region of tmRNA (transfer-mRNA), strongly suggesting it is an endo [...] (125 aa)
higAPossible antitoxin HigA; Antitoxin component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin HigB1. Neutralization of HigB1 toxin in E.coli or M.marinum also requires SecB-like chaperone Rv1957, making this the first toxin-antitoxin chaperone (TAC) system. Antitoxin aggregation and degradation are prevented by the chaperone. (149 aa)
parE1Possible toxin ParE1; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli inhibits cell growth and colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin ParD1. (98 aa)
mazF6Toxin MazF6; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and in M.smegmatis partially inhibits cell growth and colony formation; its toxic effect is neutralized by coexpression with cognate antitoxin MazE6. Acts as an mRNA interferase on ssRNA, cleaving between the second and third bases in the sequences CUCCU and UUCCU. Further experiments demonstrate that it digests between the first and second bases of UCCUU, yielding a 5'- hydroxyl end; digests M.tuberculosis mRNA (in coding as well as the 5'- and 3'-UTR regions) and 23S rRNA, digests E.coli [...] (114 aa)
higA2Transcriptional regulatory protein; Putative antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin would be HigB2. (101 aa)
hspXHeat shock protein HspX (alpha-crystallin homolog) (14 kDa antigen) (HSP16.3); Acts as a chaperone, as it has a significant ability to suppress the thermal denaturation of alcohol dehydrogenase. Cells overexpressing this gene grow more slowly than wild-type cells, and are less susceptible to autolysis following saturation of the culture in vitro, suggesting this protein may slow down the growth rate of M.tuberculosis in culture and by extension during macrophage infection. Belongs to the small heat shock protein (HSP20) family. (144 aa)
obgProbable GTP1/Obg-family GTP-binding protein Obg; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control (By similarity). GTPase activity is not inhibited by ATP or GDP. Overexpression decreases cell growth starting in late log phase and continuing into stationary phase ; Belongs to the TRAFAC class OBG-HflX-like GTPase superfa [...] (479 aa)
vapC20Possible toxin VapC20; Toxic component of a type II toxin-antitoxin (TA) system. An endoribonuclease that cleaves both E.coli and M.smegmatis 23S rRNA between G2661 and A2662 in the sarcin-ricin loop (SRL, E.coli 23S rRNA numbering). The SRL sequence is highly conserved and is implicated in GTP hydrolysis by EF-Tu and EF-G. Acts on purified ribosomes but not on isolated RNA in E.coli, nor on a shortened artificial substrate. Upon expression in E.coli inhibits cell growth, colony formation and translation. Its toxic effect is neutralized by coexpression, or subsequent expression (tested [...] (131 aa)
relAGuanosine-3',5'-bis(diphosphate) 3'-pyrophosphohydrolase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes both the formation of pppGpp, which is then hydrolyzed to form ppGpp, as well as the hydrolysis of ppGpp. RelA is probably a key factor in the pathogenesis of M.tuberculosis as it regulates the intracellular concentrations of (p)ppGpp. (790 aa)
mazF9Toxin MazF9; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis inhibits cell growth and colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin MazE9. Acts as an mRNA interferase, specifically cleaving between U and C in UAC sequences. May cleave its cognate antitoxin's gene. In E.coli expression with non- cognate antitoxins VapB27 and VapB40 partially neutralizes the toxin. Belongs to the PemK/MazF family. (118 aa)
mpt83Cell surface lipoprotein Mpt83 (lipoprotein P23); Recombinant, non-modified protein stimulates secretion of cytokines (TNF-alpha, IL-6 and IL-12p40) by mouse macrophage cell lines in a TLR2-dependent fashion, which leads to increased host innate immunity responses against the bacterium. Serves as a strong human and mouse antigen T cell antigen during M.tuberculosis infection, inducing strong IFN-gamma expression. (220 aa)
rnhBProbable ribonuclease HII protein RnhB (RNase HII); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids. (264 aa)
relJAntitoxin RelJ; Antitoxin component of a type II toxin-antitoxin (TA) system. A probable antitoxin for the putative mRNA interferase RelK. Upon expression in E.coli but not in M.smegmatis this protein neutralizes E.coli YoeB. (91 aa)
relKToxin RelK; Toxic component of a type II toxin-antitoxin (TA) system. Has RNase activity and preferentially cleaves at the 3'-end of purine ribonucleotides (By similarity). Overexpression in M.tuberculosis or M.smegmatis inhibits colony formation in a bacteriostatic rather than bacteriocidal fashion. Its toxic effect is neutralized by coexpression with antitoxin RelJ (shown only for M.smegmatis). Overexpression also increases the number of rifampcin-tolerant persister cells. Belongs to the YoeB family. (85 aa)
guaB2Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Does not catalyze the reverse reaction, i.e. the conversion of XMP to IMP. Appears to be essential for the optimal growth of M.tuberculosis. Belongs to the IMPDH/GMPR family. (529 aa)
groES10 kDa chaperonin GroES (protein CPN10) (protein GroES) (BCG-a heat shock protein) (10 kDa antigen); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family. (100 aa)
carDPossible transcription factor; Controls rRNA transcription by binding to the RNA polymerase (RNAP). Required for replication and persistence during infection of mice; Belongs to the CarD family. (162 aa)
lpqH19 kDa lipoprotein antigen precursor LpqH; Based on its structure might be involved in ligand transport (By similarity); Belongs to the mycobacterial 19 kDa antigen family. (159 aa)
esxA6 kDa early secretory antigenic target EsxA (ESAT-6); A secreted protein that plays a number of roles in modulating the host's immune response to infection as well as being responsible for bacterial escape into the host cytoplasm. Acts as a strong host (human) T-cell antigen. Inhibits IL- 12 p40 (IL12B) and TNF-alpha expression by infected host (mouse) macrophages, reduces the nitric oxide response by about 75%. In mice previously exposed to the bacterium, elicits high level of IFN-gamma production by T-cells upon subsequent challenge by M.tuberculosis, in the first phase of a protecti [...] (95 aa)
