Application
Clostripain from Clostridium histolyticum has been used as a proteolytic enzyme in perfusate to detect its effect on tube hematocrit. It has also been used in limited proteolysis of DNA polymerase (gp43) of phage T4 (RB69 gp43).
Biochem/physiol Actions
Clostripain from Clostridium histolyticum is composed of two polypeptide chains, with molecular masses of 41.7 kDa and 15.4 kDa. Clostripain has a highly restricted substrate specificity for Arg-Xaa peptide bonds. Therefore, clostripain has been explored as a potential enzyme for protein sequencing purposes. It has also been studied as a catalyst for condensation of pharmaceutically important peptides containing Arg-Pro bonds.

We demonstrate that proteases can catalyze the ligation of peptidomimetic oligomers. The enzyme clostripain was used to facilitate the native ligation of N-substituted glycine oligomers, or peptoids. In addition to mediating the efficient condensation of two peptoid fragments, iterative ligation
