Carboxypeptidase Enzyme Animal Origin Free Carboxypeptidase B
Synonyms:carboxypeptidase B; protaminase; CPB1; pancreatic
carboxypeptidase B; tissue carboxypeptidase B; peptidyl-L-lysine
[L-arginine]hydrolase; EC 188.8.131.52; 9025-24-5
Animal origin free:YaxinBio recombinant carboxypeptidase B belongs
to the AOF level 3, eliminate the risk of virus presence, or any
other potential adventitious agents found in animal-derived
Stability:A sterile recombinant carboxypeptidase B lyophilized
eliminates the risk of contamination and decreases the chances of
activity loss in the process of transport and storage.
1) Recombinant carboxypeptidase B provides increased specific
activity and eliminates contaminating proteases activities found in
extracted enzymes with lower purity level.
2) No other contaminating proteases such as chymotrypsin and
3)Less than 10ppm of recombinant trypsin.
One Unit of carboxypeptidase B activity hydrolyzes one micromole of
hippuryl-L-arginine per minute at 25℃, pH 7.65.
Carboxypeptidase B (EC 184.108.40.206, protaminase, pancreatic
carboxypeptidase B, tissue carboxypeptidase B, peptidyl-L-lysine
[L-arginine]hydrolase) is a carboxypeptidase that preferentially
acts upon basic amino acids, such as arginine and lysine. This
serum enzyme is also responsible for rapidly metabolizing the C5a
protein into C5a des-Arg, with one less amino acid.
