Rv1753c, (MTCY28.16c), len: 1053 aa. PPE24, Member of the Mycobacterium tuberculosis PPE family of Gly-,Asn-rich proteins, similar to many e.g. YF48_MYCTU|Q10778 hypothetical protein cy48.17 (678 aa), FASTA scores: opt: 1360, E(): 0, (48.9% identity in 550 aa overlap). Note that the Gly-, Asn-rich sequence is interrupted by six near-perfect 26 aa repeats, a unique region, and another,more degenerate region of five 25 aa repeats before resuming at the C-terminus. The end of the first Gly-, Asn-rich region and the start of the first set of repeats shows some similarity to Q50577|AT10S fr [...]

Probable GTP-binding protein LepA (GTP-binding elongation factor); Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

Probable chaperone protein DnaJ1; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions betwe [...]

6 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 [...]

10 kDa culture filtrate antigen EsxB (LHP) (CFP10); A secreted protein. Acts as a strong host (human) T-cell antigen. Involved in translocation of bacteria from the host (human) phagolysosome to the host cytoplasm. Might serve as a chaperone to prevent uncontrolled membrane lysis by its partner EsxA; native protein binds poorly to artificial liposomes in the absence or presence of EsxA. EsxA and EsxA-EsxB are cytotoxic to pneumocytes. EsxB (and EsxA-EsxB but not EsxA alone) activates human neutrophils; EsxB transiently induces host (human) intracellular Ca(2+) mobility in a dose-depend [...]

Two component transcriptional regulatory protein DevR (probably LuxR/UhpA-family); Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. When phosphorylated binds and activates the promoter of DevR regulon genes in response to hypoxia. The presence of target DNA increases stability of phospho-DevR in vitro. Activates its own transcription under hypoxic but not aerobic conditions, probably binds as a dimer to tandem binding sites within the devR and hspX promoters. Accepts [...]

Characterized as an oxygen sensor; O(2) acts as a switch, with O(2)-bound Fe(2+) protein inactive in autophosphorylation. Has also been suggested to act as a redox sensor, or perhaps as a dual oxygen/redox sensor. Autophosph [...]
