Also known as Clostridiopeptidase B

Clostripain (, clostridiopeptidase B, clostridium histolyticum proteinase B, alpha-clostridipain, clostridiopeptidase, Endoproteinase Arg-C) is a cysteine protease that cleaves proteins on the carboxyl peptide bond of arginine. It was isolated from Clostridium histolyticum. The isoelectric point of the enzyme is 4.8-4.9 (at 8 °C), and optimum pH is 7.4~7.8 (against α-benzoyl-arginine ethyl ester). The composition of the enzyme is indicated to be of two chains of relative molecular mass 45,000 and 12,500.
