WebMay 8, 2024 · According to the action mechanism of proteolytic enzymes and depending on the active amino acid in their active site, PIs can be divided into serine, cysteine, aspartic, and metalloprotease inhibitors . Serine PIs are competitive inhibitors and prevent the activity of serine proteases such as trypsin, chymotrypsin, and elastase. WebExample 1: Chymotrypsin An example of the ping-pong mechanism would be the action of chymotrypsin. When reacted with p-nitrophenyl acetate (A), the reaction of chymotrypsin is seen to occur in two steps. In the first step, the substrate reacts extremely fast with the enzyme, leading to the formation of a small amount of p-nitrophenolate (P).
