- 1. Hemoglobin researchers have discovered more than 500 naturally occurring hemoglobin mutations. The majority of these results from single amino acid changes. Some of these mutations result in clinical illness or symptoms, but many show no outward effects. Some examples are: HbS (sickle cell Hb)-substitutes Val for Glu on the surface Hb Cowtown - eliminates an ion pair used in T-state stabilization Hb Memphis - surface uncharged polar aa for another of similar size on the surface Hb Bibba-substitutes a Pro for a Leu in an α-helix Hb Milwaukee - substitutes a Glu for a Val Hb Providence- substitutes a Asn for a Lys that normally projects into the central cavity Hb Philly - substitutes a Phe for a Tyr, disrupting hydrogen bonding at the aß interface. EXPLAIN your choices for each of the following: a) The Hb variant least likely to cause pathological symptoms b) The variant(s) most likely to show pl values different from that of HbA c) The variant(s) most likely to show…1. How many different tripeptides are possible? How many carboxyl terminals of polypeptide chains are present in a molecule of hemoglobin? 2. You have isolated a pentapeptide composed of four glycine residues and one lysine residue that resides at the C-terminus of the peptide. Using the information provided in the legend of Figure 2.27, if the pK of the side chain of lysine is 10 and the pK of the terminal carboxyl group is 4, what is the structure of the peptide at pH 7? At pH 12? 3. The side chains of glutamic acid (pK 4.3) and arginine (pK 12.5) can form an ionic bond under certain conditions. Draw the relevant portions of the side chains and indicate whether or not an ionic bond could form at the following: (a) pH 4; (b) pH 7; (c) pH 12; (d) pH 13.What impact do mutations in the alpha-chain usually have, if any, on hemoglobin's function?

- 5. All antibodies are proteins. What protein property has favored their use as antibodies in preference to some other type of biomolecule?4. The strength of ligand-protein binding is a property of the binding site called --------------3) The ACE2 receptor protein in humans has been getting a lot of press these days, as it apparently serves as a "receptor" for the SARS-CoV-2 coronavirus in addition to its normal functions. This protein has an isoelectric pH of 5.36. Suppose you want to purify this protein to study its properties, with the goal of developing a drug that would block it from binding the virus. Once you have purified the cell surface proteins from your cultured human lung cells away from all the other types of molecules in the cell, and all the cytoplasmic proteins, you might decide to use ion exchange chromatography to separate the ACE2 proteins from other proteins in your sample. If you plan to load your protein mixture onto your ion exchange column in a buffer at pH 7.4 (approximately physiological pH) and you want the ACE2 proteins to bind to the column, should you use a resin with a positive charge or a negative charge? Briefly explain why you chose the resin you selected.
