梭菌蛋白酶 來(lái)源于溶組織梭菌, ≥50 units/mg dry weight
Product Name： Clostripain from Clostridium histolyticum
CAS號(hào):9028-00-6
介紹： 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.
用途： A protease that cleaves proteins on the carboxyl bond of arginine
貯存： 儲(chǔ)存溫度2-8℃
生化和生理學(xué)機(jī)理： 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.
