一般描述

Carboxypeptidase A-agarose product is prepared by the immobilization of carboxypeptidase A, originally isolated from the bovine pancreas, to activated 4% crosslinked beaded agarose.

生化/生理作用

Carboxypeptidase as isolated from bovine pancreas glands is a metalloenzyme that contains 1 g atom of zinc per mole of protein. It catalyzes the hydrolysis of the carboxyl-terminal peptide bond in peptides and proteins. It is primarily specific to aromatic and hydrophobic side chains such as phenylalanine, tryptophan or leucine. The enzyme also exhibits esterase activity. It is inhibited by β-phenylpropionate and indole acetate.[1]
Carboxypeptidase A is attached covalently to agarose or aldehyde and is effective for immobilization studies.[2]

单位定义

One unit will hydrolyze 1.0 μmole of hippuryl-L-phenylalanine per min at pH 7.5 at 25 °C.
