Sequencing Grade Carboxypeptidase B / Carboxypeptidase B / SRCPB

 

DESCRIPTION

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 34,500 daltons, 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.
