The following questions relate to the catalytic mechanism of chymotrypsin. Please answer all questions. a. You're working with an enzyme that is mutated (the aspartic acid in the active site is mutated to an asparagine). Please explain what the effect of this mutation would be and discuss whether this mutation would affect the activity of the mutated enzyme in comparison to the wild-type enzyme. b. What is an oxyanion hole and what's its purpose? c. Indole (shown below) has been shown to be an inhibitor of Chymotrypsin. Please suggest what type of inhibitor Indole is, draw a predicted double reciprocal plot of the Chymotrypsin alone and with Indole (highlighting the effects on Vmax and Km).
