Chymotrypsin 1000 US 1500 USP is a proteolytic enzyme, found in pancreatic juice, that catalyzes the hydrolysis of proteins into polypeptides and amino acids. CAS:9004-07-3
chymotrypsin 1000 US 1500 USPis 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. Its 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, α2-macroglobulin, 10 mM Cu2+ and Hg2+.
Chymotrypsin 1000 US 1500 USPfrom bovine has been used in a study to inform proteasome inhibition in order to advance anticancer research. α-Chymotrypsin from bovine has also been used in a study that functionalized surface anchored poly(methylhydrosiloxane) thin films on oxidized silicon wafers.
