Chymotrypsin What evidence in chymotrypsin mechanism supports the claim that chymotrypsin catalysis involves general acid-base catalysis and covalent catalysis? Draw the chemical structure of the transition state (resembles the intermediate structure) in the step that forms the enzyme-product covalent adduct. In comparison to the substrate, how is the tetrahedral transition state preferentially stabilized by enzyme? Chymotrypsin mechanism: Write all the steps in the mechanism and understand what each step accomplishes.
