Product Description
Carboxypeptidase B, also known as peptidyl-L-lysine (L-lysine) hydrolase or pancreatic carboxypeptidase B, is a specialized enzyme that hydrolyzes the amino group at the C-terminus of basic amino acids in proteins (Lysine (Lys, K), Arginine (Arg, R), and Histidine (His, H)). It has a molecular weight of 33.8 kD and an isoelectric point of 6.0, with an optimal pH range of 7.5 to 9.0. The activity of carboxypeptidase B is subject to competitive inhibition by arginine and lysine, and is inhibited by metal ion chelators such as EDTA. Yeasen UCF.ME™ R ecombinant CP B is expressed in E.coli, produced under GMP regulations, free of any animal-derived components, and without the risk of viral contamination from animal sources. The amino acid sequence is identical to that of rat pancreatic carboxypeptidase B, possessing the same enzymatic properties as the animal-derived enzyme, and can be used as a substitute in various biotechnological processes.
