Recombinant carboxypeptidase B
Genetic engineering production, no animal origin, no virus pollution, no heterozymatic pollution

1. Product introduction
Carboxypeptidase B (EC 3.4.17.2) is specifically used for the hydrolysis of basic amino acids (lysine, arginine, histidine) at the C-terminal of proteins; Also known as peptidyl-L-lysine (L-arginine) hydrolase; Protamine enzymes. The molecular weight is 35kD, the isoelectric point is 6.0, and the optimal pH is 7-9. The activity is competitively inhibited by arginine and lysine, and metal ion chelators such as EDTA inhibit enzyme activity.

2. Product advantages
No animal origin: recombinant production, no exogenous virus contamination, such as swine influenza virus, porcine parvovirus, etc
High purity: no other heterozymatic activity: no other side reactions in the digestion reaction, high yield
Specific live height: not less than 120 u/mg pro.; not less than 170 u/mg pro.
Electrophoresis purity: SDS-PAGE electrophoresis identification, 95%
Stable: lyophilized powder, easy to store and transport

3. Product use
Production of recombinant insulin and its analogues
Determination of protein C-terminal amino acids
Production of other recombinant peptides
Enzymatic synthesis of certain special compounds
