Clostripain (, 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. It was isolated from Clostridium histolyticum.
Clostripain, also called alpha-clostridipain or clostridiopeptidase, is an enzyme found in Clostridium histolyticum. This proteinase specifically cleaves proteins at the carboxyl end of arginine bonds.
