Animal components free carboxypeptidase B for Protein structure and sequence analysis
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 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 (EC 3.4.17.2) 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.
