Question 2. An enzyme was found to convert Acetyl-coA to an acetyl-cysteine intermediate of theenzyme. The structure of cOA is:HHНО СН;HS — СH2— СH2 — N—C—CH,— CH2—N- С—С—С—CH;—0—Р-0–CH2Adenineн CHHHHPhosphopantetheine group of coenzyme A2-O3POОНDraw a plausible chemical mechanism. Where is the acetyl-group in acetyl-coA? What is the reactivegroup of the protein? The reaction is enhanced at higher pH. How is this consistent with yourmechanism? Is covalent catalysis involved?
