应用

α-Chymotrypsin agarose from bovine pancreas has been used to study the purification and characterization of glucoamylase. α-Chymotrypsin agarose from bovine pancreas has also been used in a study to investigate molecular modeling for the design of a biomimetic chimeric ligand.

生化/生理作用

α-Chymotrypsin is a serine peptidase and has 241 amino acid residues contained in three polypeptide chains (A chain-13 residues, B chain-131 residues, and C chain-97 residues) linked by disulfide bridges. Molecular weight of this enzyme is found to be 25 kDa. The pI is 8.75. It selectively hydrolyzes peptide bonds on the C-terminal side of tyrosine, phenylalanine, tryptophan, and leucine. Ca2+ activates and stabilizes the enzyme. The enzyme is inhibited by diisopropyl fluorophosphate (DFP), phenylmethanesulfonyl fluoride (PMSF), N-p-tosyl-L-phenylalanine chloromethyl ketone (TPCK), chymostatin, aprotinin, α1-antitrypsin, and α2-macroglobulin, 10 mM Cu2+ and Hg2+.
Serine protease that hydrolyzes peptide bonds with aromatic or large hydrophobic side chains (Tyr, Trp, Phe, Met) on the carboxyl end of the bond.

单位定义

One unit will hydrolyze 1.0 μmole of N-acetyl-L-tyrosine ethyl ester (ATEE) per min at pH 8.0 at 30 °C.

Molecular modeling was employed for the design of a biomimetic chimeric ligand for L-lactate dehydrogenase (LDH). This ligand is an anthraquinone monochlorotriazinyl dye comprising two moieties: (a) the ketocarboxyl biomimetic moiety, 2-(4-aminophenyl)-ethyloxamic acid, linked on the monochlorotriazine ring, mimicking the
