Beschreibung

Anwendung

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.

Biochem./physiol. Wirkung

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.

Einheitendefinition
