General description
α-Chymotrypsin from bovine pancreas (bovine pancreatic α-chymotrypsin, CHT) is an enzyme protein. The influence of varying concentrations of organic solvents like ethanol, 1,4-dioxane and acetonitrile on CHT has been reported.
Chymotrypsin (Chy) is a serine protease. It corresponds to a molecular weight of 25.7 kDa and is widely used in pharmaceutical industry. It is synthesized in pancreas from chymotrypsinogen and require calcium for this conversion.
Application
α-Chymotrypsin from bovine pancreas is used for the following applications:
- Protein Identification by mass spectrometry (MS)
- The isolation and characterization of myosin heavy chains
- Toxin preparation
- The incubation of infected and uninfected cells for analysis of cellular proteins by SDS-PAGE
Biochem/physiol Actions
A serine protease that hydrolyzes peptide bonds with aromatic or large hydrophobic side chains (Tyr, Trp, Phe, Met, Leu) on the carboxyl end of the bond.
α-Chymotrypsin from bovine pancreas is stabilized by Ca2+ and catalyzes the hydrolysis of peptide bonds in particular the amino acids tyrosine, phenylalanine, tryptophan, and leucine at their C-terminal side. α-Chymotrypsin is inhibited by Cu2+ and Hg.
Other Notes
One unit will hydrolyze 1.0 μmole of BTEE per min at pH 7.8 at 25 °C.
