- | Trypsin is serine protease which catalyzes the hydrolysis of peptide bonds of a substrate via an acylation reaction and a deacylation reaction. In the first (acylation) reaction, the nucleophilic serine attacks the substrate scissile bond, forming a tetrahedral intermediate and then a covalent acyl-enzyme with the release of the C-terminal fragment. In the second (deacylation) reaction, a water molecule attacks the acyl-enzyme, leading to a second tetrahedral intermediate followed by release of the N-terminal fragment. The specificity of substrates is determined by the structure of its specificity pocket, which contains Ser 195, His 57, and Asp 102. These three residues make up the <scene name='72/725340/Catalytic_triad/1'>Catalytic Triad</scene | + | Trypsin is serine protease which catalyzes the hydrolysis of peptide bonds of a substrate via an acylation reaction and a deacylation reaction.
