From a kinetics experiment, the Vmax was determined to be 450µM∙min-1. For the kinetic assay, 0.1mL of a 0.05mg/mL solution of enzyme was used, and the enzyme has a molecular weight of 125,000 g/mole. Assume a reaction volume of 700µL. Calculate the kcat (in sec-1) for the enzyme.

From a kinetics experiment, kcat was determined to be 295sec-1. For the kinetic assay, 0.3mL of a 0.25mg/mL solution of enzyme was used, and the enzyme has a molecular weight of 125,000 g/mole. Assume a reaction volume of 3mL. Calculate Vmax (µM∙min-1) for the enzyme and catalytic efficiency ( in M-1sec-1) for the enzyme. The Km for the enzyme was determined to be 2.55 x 10-2M.
The absorption of ketoconazole has been shown to be impaired in patients with drug-induced achlorhydria. The drug absorption was increased significantly to approximately 65% when the drug was taken with an acidic beverage such as Coca-Cola (pH 2.5). Ketoconazole is a synthetic azole antifungal agent and a weakly dibasic compound with pKa of 2.9 and 6.5. Using the information provided and the pH partition hypothesis, justify the use of Coca-Cola to improve the absorption of this antifungal agent.

A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction The researchers begin to characterize the enzyme. (a) In the first experiment, with [Et] at 4 nM, they find that the Vmax is 1.6 uM/s. Based on this experiment, what is the kcat for happyase*? (Include appropriate units.) (b) In another experiment, with [Et] at 1 nM and [HAPPY] at 30 uM, the researchers find that V0 = 300 nM/s. What is the measured Km of happyase* for its substrate HAPPY? (Include appropriate units.) (c) Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation and the two experiments repeated, the measured Vmax in (a) is increased to 4.8 uM/s, and the measured Km in (b) is now 15 uM. Based on this information, can you figure out what type of inhibitor is ANGER? (Use table 6.9 at the end of the…

A simple biochemical reaction with three molecules has solutions that oscillate toward a steady state when positive constants a and b are below the curve b - a = (b + a)3. Find the largest possible value of a for which the reaction has solutions that oscillate toward a steady state. (Hint: Find where da/db = 0. Derive values for a + b and a - b, and then solve the equations in two unknowns.) Source: Mathematical Biology.
