One of the ways we know about the mechanism of enzymes is through the use of xray crystallography structures of trapped intermediates or inhibitors bound to enzymes. In a paper by Radisky and Koshland<ref>PMID: 16636277</ref>, an acyl intermediate of trypsin (PDB code [[2AGG]] was characterized.

Serine proteases use a covalent mechanism to catalyze the hydrolysis of a peptide bond.  A covalent bond is formed between <scene name='72/725330/Ser195/1'>Ser195</scene> and a substrate <scene name='72/725330/Substrate_and_ser/1'>peptide</scene>.


Specificity of the proteases is determined by a binding pocket.
