Detailed Product Description
Source : E. Coli Purified by : HPLC
Specific activity  : ≥170 Units/mg Pro. Purity : > 95%
Protein content: 35% ~ 50% Cat. No: RCPB01
Impact: Insulin Processing Production

Recombinant Carboxypeptidase B which insulin processing production needs


Insulin production enzymes - Carboxypeptidase B


Catalog Number:RCPB01

Source: Expressed in E. Coli.




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.





Animal origin free:YaxinBio recombinant carboxypeptidase B belongs to the AOF level 3, eliminate the risk of virus presence, or any other potential adventitious agents found in animal-derived carboxypeptitase B


Stability:A sterile recombinant carboxypeptidase B lyophilized eliminates the risk of contamination and decreases the chances of activity loss in the process of transport and storage.


High purity:

1) Recombinant carboxypeptidase B provides increased specific activity and eliminates contaminating proteases activities found in extracted enzymes with lower purity level.

2) No other contaminating proteases such as chymotrypsin and carboxypeptidase A.

3)Less than 10ppm of recombinant trypsin.

Carboxypeptidase B (EC, 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.
