Function

[SSPA_STAAM] Preferentially cleaves peptide bonds on the carboxyl-terminal side of aspartate and glutamate. Along with other extracellular proteases it is involved in colonization and infection of human tissues. Required for proteolytic maturation of thiol protease SspB and inactivation of SspC, an inhibitor of SspB. It is the most important protease for degradation of fibronectin-binding protein (FnBP) and surface protein A, which are involved in adherence to host cells. May also protect bacteria against host defense mechanism by cleaving the immunoglobulin classes IgG, IgA and IgM. May be involved in the stability of secreted lipases (By similarity).

Publication Abstract from PubMed

V8 protease, an extracellular protease of Staphylococcus aureus, is related to the pancreatic serine proteases. The enzyme cleaves peptide bonds exclusively on the carbonyl side of aspartate and glutamate residues. Unlike the pancreatic serine proteases, V8 protease possesses no disulfide bridges. This is a major evolutionary difference, as all pancreatic proteases have at least two disulfide bridges. The structure of V8 protease shows structural similarity with several other serine proteases, specifically the epidermolytic toxins A and B from S. aureus and trypsin, in which the conformation of the active site is almost identical. V8 protease is also unique in that the positively charged N-terminus is involved in determining the substrate-specificity of the enzyme.
