Serine protease Hip1

UniProtKB accession:  P9WHR3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Serine protease that promotes tuberculosis (TB) pathogenesis by promoting the processing and the extracellular release of the M.tuberculosis (Mtb) heat-shock protein GroEL2 (PubMed:18172199, PubMed:24830429, PubMed:28346784). Hip1-dependent cleavage of multimeric GroEL2 results in release of cleaved monomeric GroEL2 into the extracellular milieu. Conversion of multimeric GroEL2 into monomeric GroEL2 is likely to be a mechanism for regulating GroEL2 functions during Mtb pathogenesis (PubMed:24830429). In vitro, exhibits proteolytic activity against synthetic peptides and the general protease substrate azocasein, and exhibits esterase activity against the ester substrate p-nitrophenylbutyrate (PubMed:24830429, PubMed:28346784).
