Description

Biochem/physiol Actions

Trypsin plays an important role in the digestion of consumed protein and contributes to the activation of other proteolytic enzymes like chemotrypsin and elastase.[1]

General description

Trypsin is a major proteolytic enzyme, synthesized as a preproenzyme by pancreas and is stored as proenzyme trypsinogen in secretory granules.[1] Trypsin belongs to the family of serine proteases that are characterized by the catalytic triad His57, Asp102 and Ser195.[2] Trypsin is routinely used in proteomics research for peptide mapping and protein sequence work due to its highly specific cleavage resulting in a limited number of tryptic peptides. Trypsin is a pancreatic serine endoprotease which hydrolyzes peptide bonds specifically at the carboxyl side of arginine and lysine residues.[3] The rate of hydrolysis is slower if an acidic residue is on either side of the cleavage site and cleavage may not occur if a proline residue is on the carboxyl side. The enzyme also exhibits esterase and amidase activities. Trypsin has an average molecular mass of 23.29 kDa and a pH optimum near 8.0. This product is prepared from recombinant trypsin, porcine sequence. It is naturally devoid of chymotryptic activity. This high-quality trypsin is suitable for proteomics use.
