Descrição geral

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.

Aplicação

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
α-Chymotrypsin from bovine pancreas (BPC) may be used as a catalyst in the preparation of tetrahydroquinoline derivatives by Povarov reaction.

Ações bioquímicas/fisiológicas

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.
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.

Definição da unidade

One unit will hydrolyze 1.0 μmole of BTEE per min at pH 7.8 at 25 °C.
