Recombinant Carboxypeptidase B

Recombinant Carboxypeptidase B
Product 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, pI is 6.0 and the optimum pH is 7.5-9.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA. YaxinBio has cloned rat carboxypeptidase B gene into  E.coli for expression with equivalent properties compared to animal original carboxypeptidase B .Recombinant carboxypeptidase B can replace native carboxypeptidase B for using in a variety of biotechnological processes. 


The production of recombinant insulin and its analogues;

the quality test of recombinant antibodies;

the determination of C-terminal amino acids of proteins;

the production of other recombinant polypeptides;

and the enzymatic synthesis of certain specific compounds.

    Recombinant carboxypeptidase B eliminates the risk of viruses, or other potential adventitious agents found in animal derived carboxypepitdase B. Which belong to the AOF level 3 products.

    A sterile recombinant carboxypeptidase B lyophilized powder eliminates the contamination opportunity and decreases the chance of activity loss in the process of transport and storage. Convenient for transport and store.

    High purity

    1)Recombinant carboxypeptidase B provides increased specificity and eliminates contaminating activities found in lower purity enzymes
    2)No other proteases contaminated such as chymotrypsin, carboxypeptidase A, and the content of recombinant trypsin less than 10ppm.
    3)One single main band at 35kD by SDS-PAGE.
