I. Active site analysis. Below is a diagram of a putative active site for Monoamine oxidase. As we learned, the purpose of tertiary structure is to form a scaffold so you can orient just a few amino acids in the right orientation to promote binding and/or catalysis. The position where this occurs is the active site. The amino acid architecture of an active site is designed to bind substrates. Amino acid side chains are capable of hydrogen bonding, ionic and hydrophobic interactions. Fill in each amino acid that you think is suitable for interacting with the part of the substrate it is closest to. Assume the pH will be at 7.0 a.a.#1 a.a.#2 a.a.#6 HO Lond NH₂ НО a.a.#5 OH a.a.#3 a.a.#4

in human 2. Human xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. For the treatment of hyperuricemia and gout. several medications are used to inhibit the activity of xanthine oxidase and reduce the production of uric acid. You are a biochemist and just discovered a chemical that can inhibit the activity of the human xanthine oxidase. When analyzing its mode of inhibition, you found that the enzyme inhibitor complex requires 450 kJ.mol to dissociate and that it displays kinetics somehow similar to noncompetitive inhibition. You sent your inhibitor to the ministry of health for approval as a medication for gout. Based on the data provided, are they going to authorize it as a medication or not? Explain?
