Clostripain (EC 3.4.22.8, clostridiopeptidase B, clostridium histolyticum proteinase B, alpha-clostridipain, clostridiopeptidase, Endoproteinase Arg-C) is a proteinase that cleaves proteins on the carboxyl peptide bond of arginine.[1][2][3] It was isolated from Clostridium histolyticum. The optimum pH of the enzyme is 7.4~7.8.
