animal origin free carboxypeptidase B,carboxypeptidase B lyophilized powder
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.
