Question 2. Draw the following mechanisms. You must clearly show all atoms and curly arrows. a. Draw the side chain of a histidine acting as a base to remove proton from water. Then the resulting hydroxide acts as a nucleophile to attack the carbonyl of the molecule acetone, forming a tetrahedral intermediate b. Draw a deprotonated serine attacking the carbon of a peptide bond, forming a covalent tetrahedral intermediate, then show the collapse of the tetrahedral intermediate and cleavage of the peptide bond such that the departing amine is protonated by a nearby glutamic acid to facilitate its departure.
