描述
应用 | Carboxypeptidase B has been used in a study to develop a non-invasive pregnancy assay for use in both captive and wild polar bears. Carboxypeptidase B has been used in a study that identified new potential biomarkers of acute pancreatitis. |
产品介绍 | Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and ornithine from the C-terminal end of polypeptides. The molecular weight is 34,500 daltons, the pH optimum is 7.9, and the pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine, lysine and ornithine. The enzyme is not inhibited by di-isopropylfluorophosphate (DFP), but it is inhibited by metal chelating agents, e.g., 1,10-phenanthroline. |
备注 | A solution in 100mM sodium chloride. PMSF treated to inhibit tryptic and chymotryptic activities. Chymotrypsin and trypsin are less than 0.02%. |
生化机理 | Carboxypeptidase B is a proteolytic enzyme capable of rapidly hydrolyzing peptide bonds to release certain carboxyl-terminal basic amino acids from peptides and proteins. Its molecular mass is 34,300±600 Da. It contains one non-dialyzable gram atom of zinc per mole. The enzyme activity is inhibited by metal chelating agents 1, 10-phenanthroline, 8-hydroxyquinoline-5-sulfonic acid, and 2,2’-dipyridyl. |
