Clostripain (Endoproteinase-Arg-C) is a two chain proteinase associated with collagenase and isolated from?Clostridium histolyticum. It is highly specific for the carboxyl peptide bond of arginine. Clostripain has a sulfhydryl requirement; it is activated by dithiothreitol, cysteine, or other sulfhydryl containing reagents. The presence of calcium ions is essential. The enzyme is inhibited by oxidizing agents and sulfhydryl reactants and by Co2+, Cu2+, Cd2+, and heavy metal ions. Citrate, borate, and Tris anions are less inhibitory.
