Recombinant Carboxypeptidase B
CAS:9025-24-5
EC:3.4.17.2
Genetic engineering production, no animal origin, no virus pollution, no miscellaneous enzyme pollution
1. Product introduction
Carboxypeptidase B (EC 3.4.17.2) is exclusively used for the hydrolysis of protein C-terminal basic amino acids (lysine, arginine, histidine); also known as peptidyl-L-lysine (L -Arginine) hydrolase; sperminase. The molecular weight is 35kD, the isoelectric point is 6.0, and the optimum pH is 7-9. The activity is competitively inhibited by arginine and lysine, and metal ion chelating agents such as EDTA inhibit enzyme activity.
2. Product advantages
No animal origin: recombinant production, no foreign virus contamination, such as swine flu virus, porcine parvovirus, etc.
High purity: no other miscellaneous enzyme activity: no other side reactions in the digestion reaction, high yield
High specific activity: no less than 120 u/mg pro.; no less than 170 u/mg pro.
Electrophoresis purity: SDS-PAGE electrophoresis identification, 95%
Stable: freeze-dried powder, easy to store and transport
