Description

Stable Recombinant Carboxypeptidase B E.coli? Carboxypeptidase B E.coli

?

?
Description ? Carboxypeptidase B (or peptidyl-L-lysine (-L-arginine) hydrolase) catalyzes the hydrolysis of the basic amino acids, lysine, arginine, and ornithine from the C-terminal position of polypeptides. It has been shown to be a single polypeptide of 33.8 kDa. Trypsin is capable of converting native enzyme to the active enzyme, carboxypeptidase B II in vitro. The optimum pH is found to be 9.0. The enzyme may be used for sequence analysis by successive cleavage of C-terminal basic amino acids. It can also be used as a serum marker for the diagnosis of acute pancreatitis. Synonyms:carboxypeptidase B; protaminase; CPB1; pancreatic carboxypeptidase B; tissue carboxypeptidase B; peptidyl-L-lysine [L-arginine]hydrolase; EC 3.4.17.2; 9025-24-5 GeneID:113936 mRNA:Refseq NM_053617 Protein Refseq NP_446069 UniProt ID Q9EQV9 Chromosome Location:15q11 Pathway:Compl ?
Advantages

?

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 carboxypeptitase B

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.

High purity:

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 carboxypeptidase A.

3)Less than 10ppm of recombinant trypsin.
