For this reason, a zymogen is also called a proenzyme. The active site is the key feature of an enzyme. It is the place where the molecule that the enzyme acts on, called the substrate, binds and undergoes chemical change.An enzymeâs active site and overall function is dependent on the shape of the enzyme.hen the zymogen is in the presence of an enzyme specifically designed to breakdown peptides, called a protease, some of the amino acids are removed.
