| Enzyme Function | FUNCTION: Serine protease that promotes tuberculosis (TB) pathogenesis by promoting the processing and the extracellular release of the M.tuberculosis (Mtb) heat-shock protein GroEL2 (By similarity). In vitro, catalyzes the cleavage of ester bonds. Esterase activity increases with increasing carbon chain length of the substrate (PubMed:17428787). {ECO:0000250|UniProtKB:P9WHR3, ECO:0000269|PubMed:17428787}.; FUNCTION: Key immunomodulatory virulence factor, which promotes survival in host macrophages and modulates host immune responses. {ECO:0000250|UniProtKB:P9WHR3}. |
