| | PE5 | PE family protein PE5; Important for the siderophore-mediated iron-acquisition function of ESX-3. May play a pivotal role in the evasion of host immune response by M.tuberculosis. Mediates production of IL-10 via activation of the p38 and ERK1/2 mitogen-activated protein kinase (MAPK) signaling pathways. (102 aa) |
| | PPE4 | PPE family protein PPE4; Important for the siderophore-mediated iron-acquisition function of ESX-3; Belongs to the mycobacterial PPE family. (513 aa) |
| | esxG | ESAT-6 like protein EsxG (conserved protein TB9.8); EsxG, in complex with EsxH, 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. EsxG stabilizes EsxH in the host cytosol. (97 aa) |
| | esxH | Low 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) |
| | espG3 | ESX-3 secretion-associated protein EspG3; Specific chaperone for cognate PE/PPE proteins. Plays an important role in preventing aggregation of PE/PPE dimers. (295 aa) |
