Enzymes Recombinant Carboxypeptidase B E.coli Digestion of Protein and Polypeptide

Recombinant Carboxypeptidase B


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.

Main Features


E. Coli

Purified by



White or white-like or yellowish lyophilized


Tris salts, NaCl salts and carbohydrates


Single main band on SDS-PAGE



Contaminant activity

Less than 10 ppm of recombinant trypsin.

Unit Definition:One Unit of carboxypeptidase B activity hydrolyzes one micromole of hippuryl-L-arginine per minute at 25℃, pH 7.65.


① Animal origin free: Recombinant carboxypeptidase B is no exogenous virus contamination,and any animal origin material is not used in the production process.

② Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.

③ High purity: Higher specific activity.No other contaminating proteases such as chymotrypsin and carboxypeptidase A.Host protein residues is less than the limits of biological products.

④ Lyophilized powder: The product is lyophilized powder and is convenient to store and transport.

⑤ Compliance with regulatory requirements: Production equipment and production environment comply with relevant regulatory requirements, and the production process is in full compliance with NSF ISO 9001: 2015 quality system and GMP guidelines.

⑥ Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.
