Recombinant Carboxypeptidase B

 

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 pH optimum 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.

 

Recommend Usage

 

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 no activity lose after 10 times repeated freezing and thawing.
