comments
This enzyme belongs to the peptidase family S10.
According to the literature [2], this enzyme contains a catalytic triad, Ser146/Asp338/His397 (PDB; 1cpy), which is similar to those of trypsine-like serine peptidases. In this enzyme, Ser146 acts as a nucleophile, and His397 acts as Acid/Base. The negatively charged tetrahedral intermediate during catalysis is stablized by the oxyanion hole composed of the backbone amides.
