1-The unmutated form of your protein has a Km of 25 µM and a Vmax of 43 mM/s. The enzyme kinetic data for your enzyme with the amino acid substitution should now be displayed in the table above. Based on these data, explain the effect of amino acid substitution on the Km and Vmax for the mutated protein. (Up to 50 words)
You are not expected to draw a Lineweaver-Burk plot, however a quick sketch of a Vi vs [S] plot may help you to answer the question
2-A transmembrane protein uses a β barrel structure to span the cell membrane. How can amino acid mutations in a protein within this β barrel structure affect interactions with the membrane and why? (Up to 50 words)

An enzyme has a KM of 20 µM and a Vmax of 50 mmoles of product/minute/µg of enzyme. After exposure to an inhibitor and analysis on a Lineweaver - Burk plot the following values are obtained: -1/KM = - 0.05 liters/µmole and 1/Vmax = 0.04 (mmoles of product/minute/µg of enzyme)-1. What kind of inhibitor was used in the experiment?

1. The HIV-1 protease, an important enzyme in the life cycle of the human immunodeficiency virus-1 (HIV-1), is a good drug target for the treatment of HIV and AIDS. A protein produced by the virus, p6*, is an HIV-1 protease inhibitor. The activity of the HIV-1 protease was measured in the presence and absence of p6* using an assay involving an artificial substrate, as shown below. NH Lys...

1. Radioactive (14C) uridine (lots of it) is added to a growing culture of bacteria for 10 seconds and then the drug rifamycin is added (rifamycin blocks the initiation of transcription, but not continued elongation of RNA polymerases that have already begun transcribing). At two-minute intervals, 1 ml samples are removed and placed on ice. The bacteria are lysed (broken open) and an enzyme is added that will chew up all...
