9025-24-5 Usage
Uses
Different sources of media describe the Uses of 9025-24-5 differently. You can refer to the following data:
1. The enzyme from Sigma has been used to develop homogeneous time-resolved fluorescence (HTRF) assay for measuring carboxypeptidase B activity in a miniaturized high-throughput screening format. It has been used to evaluate the impact of the C-terminal lysine(s) in human plasminogen binding to Bifidobacterium. The effect of treatment with carboxypeptidase B, which is a C-terminal lysine-specific endopeptidase, is measured using flow cytometry analysis.
2. Carboxypeptidase B from Sigma has been used as a reference for assaying carboxypeptidase activity in lysed pituitary granules derived from the anterior and intermediate lobes of rat. The enzyme has also been used to digest plasma samples by removing C-terminal basic amino acids, to get a distinct band for each allotype during C4 electrophoresis.
General Description
Native carboxypeptidase B catalyzes the release of C-terminal from basic amino acids, arginine, lysine, or ornithine from polypeptides. Inhibited by EDTA and other Zn2+ chelators.
Biochem/physiol Actions
Carboxypeptidase B is a proteolytic enzyme capable of rapidly hydrolyzing peptide bonds to release certain carboxyl-terminal basic amino acids from peptides and proteins. Its molecular mass is 34,300±600 Da. It contains one non-dialyzable gram atom of zinc per mole. The enzyme activity is inhibited by metal chelating agents 1, 10-phenanthroline, 8-hydroxyquinoline-5-sulfonic acid, and 2,2′-dipyridyl.
Check Digit Verification of cas no
The CAS Registry Mumber 9025-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,2 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9025-24:
(6*9)+(5*0)+(4*2)+(3*5)+(2*2)+(1*4)=85
85 % 10 = 5
So 9025-24-5 is a valid CAS Registry Number.
