1. Consider the three-dimensional model of the tertiary structure of an enzyme below. Amino acids involved in binding are shaded blue, and amino acids involved in catalysis are shaded red. A. Suppose research has shown that amino acid 82 in the red shaded region is lysine, an amino acid with a positively-charged side chain. This lysine is critical for catalysis. Other studies have found that amino acids 12 and 62 in the blue region are both phenylalanine, an amino acid with a nonpolar side chain, and are critical for substrate binding. These amino acids are relatively close in the active site but are separated by 20-70 amino acids in the primary structure. Using what you know about protein structure, explain how amino acids separated in the primary structure can come close together in the active site. B. Use this information and figure 4.2 in your book to answer the following questions: Do you think changing amino acid 82, lysine, an amino acid with a positively-charged side…

complete the following mechanism showing the cleavge of the peptide bond for the following cysteine protease reaction. you only need a catalytic dyad for cystein proteases because the pKa of cysteine is low enough (8) and close enough to the pH of 7.4 that is can easily be deprotonated by histidine.

Consider the hypothetical biochemical pathway shown below. Assume that each letter (A, B, C, etc) represents a molecule and each number (1, 2, 3, etc) represents an enzyme. Draw arrows indicating all the probable feedback inhibition interactions that would be expected to regulate the activity of enzymes in this pathway.
3. Below is an image of sucrose. HO OH OH HO- HO OH OH НО (a) Using sucrose as a substrate, draw a schematic reaction for a general glycosidase. Explain whether your mechanism corresponds to an inverting or a retaining type enzyme. C :) (b) The two products can occur in a range of forms in solution. How many forms might you expect in this case, and explain how these interconvert. C 2
Use the given experimental data to deduce the sequence of anoctapeptide that contains the following amino acids: Ala, Gly (2 equiv),His (2 equiv), Ile, Leu, and Phe. Edman degradation cleaves Gly from theoctapeptide, and carboxypeptidase forms Leu and a heptapeptide. Partialhydrolysis forms the following fragments: Ile–His–Leu, Gly, Gly–Ala–Phe–His, and Phe–His–Ile.
Which of the following statements about the allosteric site is true? a. The allosteric site is a second active site on a substrate in a metabolic pathway. b. The allosteric site on an enzyme can allow the product of a metabolic pathway to inhibit that enzyme and stop the pathway. c. When the allosteric site of an enzyme is occupied, the reaction is irreversible and the enzyme cannot react again. d. An allosteric activator prevents binding at the active site. e. An enzyme that possesses allosteric sites does not possess an active site.
