Description
Trypsin (EC 3.4.21.4) is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyses proteins. Trypsin is produced in the pancreas as the inactive protease trypsinogen. Trypsin cleaves peptide chains mainly at the carboxyl side of the amino acids lysine or arginine, except when either is followed by proline. It is used for numerous biotechnological processes. The process is commonly referred to as trypsin proteolysis or trypsinisation, and proteins that have been digested/treated with trypsin are said to have been trypsinized.
Abbr
Trypsin, Native (Human)
Applications
Trypsin has been used in a study to assess the similarities between the hepatitis E virus and human astrovirus. Trypsin has also been used in a study to characterize a unique technique for culturing primary adult human epithelial progenitor, or stem, cells.
