Clostripain
Clostripain is a proteinase 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, and optimum pH is 7.4~7.8. The composition of the enzyme is indicated to be of two chains of relative molecular mass 45,000 and 12,500.
