Structue of V8 Protease from Staphylococcus aureus
Overview
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.
