Description

Carboxypeptidase B: A ZINC-dependent carboxypeptidase primary found in the DIGESTIVE SYSTEM. The enzyme catalyzes the preferential cleavage of a C-terminal peptidyl-L-lysine or arginine. It was formerly classified as EC 3.4.2.2 and EC 3.4.12.3. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Research Excerpts

Overview

Carboxypeptidase B is a metalloenzyme, which is widely used for commercial and research purposes. It hydrolyzes C-terminal alkaline amino acid of a peptide.

Treatment

Carboxypeptidase B treatment eliminated the increment in the plasminogen binding capacity of the nonadherent cells. The increase in binding was due to exposure of new carboxyl-terminal lysyl residues on the cell surfaces.
