WebStringent specificity of trypsin activity is crucial for protein identification. However, specificity can be compromised by autolysis, which generates pseudotrypsin with a broadened specificity and chymotrypsin-like activity (Keil-Dlouha et al., 1971). Autolysis can result in additional peptide fragments that could interfere with database analysis and … WebMar 4, 2024 · Trypsin is a member of the serine protease S1 family. It consists of a single chain polypeptide of 223 amino acid residues. The native form of trypsin is refered to as β-trypsin. Autolysis of β-trypsin (which is cleaved at Lys 131 - Ser 132 in the bovine sequence) results in α-trypsin which is held together by disulfide bridges.
