Description
?
Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and histidine from the C-terminal end of polypeptides. The molecular weight is 33.8kD, the optimum pH is 8.0, and pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA. Recombinant Carboxypeptidase B is expressed in E.Coli?and purified by high pressure liquid chromatography. There is no trace of other enzyme (such as carboxypeptidase A and chymotrypsin) activity. No protease inhibitors such as PMSF are present in the preparation.

Unit? Definition
?
One Unit of carboxypeptidase B activity hydrolyzes one micromole of??hippuryl-L-arginine per minute at 25℃, pH 7.65.
? Applications ? Carboxypeptidase B (EC 3.4.17.2, protaminase, pancreatic carboxypeptidase B, tissue carboxypeptidase B, peptidyl-L-lysine [L-arginine]hydrolase) is a carboxypeptidase that preferentially acts upon basic amino acids, such as arginine and lysine. This serum enzyme is also responsible for rapidly metabolizing the C5a protein into C5a des-Arg, with one less amino acid.
?
Recommend? Usage
?
To prepare 1-10mg/ml carboxypeptidase B with sterile water or 25mM Tris-HCl pH 7.65. The ratio to aimed protein is 1:50 to 1:1000 (w/w), the optimum pH is pH?7-9.
?
Storage Instructions
?
Recommend recombinant carboxypeptidase B lyophilized?should be stored under 2℃-8℃ in sealed container. It is stable within 24 months.After dissolved, it should be stored under -20℃, It is stable within 24 months and above 90%?activity remained?after 10 times repeated freezing and thawing.
? Pathway ? Complement and Coagulation Cascades, organism-specific biosystem; Complement and coagulation cascades, conserved biosystem; Protein digestion and absorption, organism-specific biosystem ? Function ? carboxypeptidase activity; metallocarboxypeptidase activity; zinc ion binding
