描述

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.
别名	;Peptidyl-L-lysine(L-arginine) hydrolase;Protaminase
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.
备注	Chromatographically purified. A solution in 100mM sodium chloride. Chymotrypsin and trypsin 0.02%.
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.
