3. (Part A) The intermediates of a pathway are shown in the following scheme. Using curved arrows, show the mechanism of each step labeled with a blue letter. Draw out the structures of all coenzymes, so that you can effectively show all arrow pushing. You may abbreviate the coenzymes by putting R groups on the molecule, but do draw out the parts of the structure that are involved in the arrow pushing. Please note that some of the transformations will require you to show multiple structures to show all of the arrow pushing (particularly some of the coenzyme-mediated steps). You do not need to show specific amino acid residues that perform the catalysis. You can abbreviate acidic amino acid residues "Enz-B-H" and basic residues "B-Enz".

Which of the following is most likely correct for this pathway? A) Either metabolite U or V is likely to be a positive modulator, increasing the activity of X. B) The first product S, is probably the primary negative modulator of X, leading to feedback inhibition. C) The last product, W, is likely to be a negative modulator of X, leading to feedback inhibition. D) The last product, W, is likely to be a positive modulator, increasing the activity of Х. E) The last reaction will be catalyzed by a second regulatory enzyme.

1. Substrates and reactive groups in an enzyme’s active site must be precisely aligned in order for a productive reaction to occur. Why, then, is some conformational flexibility also a requirement for catalysis? 2. Some plants contain compounds that inhibit serine proteases. It has been hypothesized that these compounds protect the plant from proteolytic enzymes of insects and microorganisms that would damage the plant. Tofu, or bean curd, possesses these compounds. Manufacturers of tofu treat it to eliminate serine protease inhibitors. Why is this treatment necessary?
