Aplicación
Carboxypeptidase B has been used in a study to develop a non-invasive pregnancy assay for use in both captive and wild polar bears. Carboxypeptidase B has been used in a study that identified new potential biomarkers of acute pancreatitis.
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.[1] 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]
Acciones bioquímicas o fisiológicas
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.[3]
