Trypsin: an example of a serine protease

Trypsin is a serine protease. It works with a catalytic triad of aspartic acid, histidine and serine to catalyze the formation of a covalent intermediate with the substrate. This structure shows the binding of trypsin to a competitive inhibitor, leupeptin. There is a hydrophobic binding pocket to help align the substrate protein with the enzyme, and an oxyanion hole to stabilize the intermediate.
