PPE family protein PPE18; Could be a crucial virulence factor for intracellular survival of M.tuberculosis. Favors development of Th2-type response, and downregulates the proinflammatory and Th1-type response. Specifically interacts with the human Toll-like receptor 2 (TLR2), leading to an early and sustained activation of p38 MAPK, which induces IL-10 production and activates Th2-type immune response. Also inhibits proinflammatory cytokines IL-12p40 and TNF-alpha production. Acts by upregulating the expression as well as tyrosine phosphorylation of suppressor of cytokine signaling 3 ( [...]

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.

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 [...]

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.

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 [...]
