Calculate KI' of the inhibitor from the information given. All information may not be needed to calculate. K'm = (29Ki+1.45x10^-10)/Ki Vmax = 11.7 µMs-1 Kcat = 130 s^-1 Vo = 3.0 μMs-1 S = 10 μM Et = 0.09 µM Inhibitor Concentration = 5x10^-12
A new drug, Proinebrium, that reduces Kcat (Ki = 2.0 uM) has been developed to treat ethylene glycol poisoning. (1) What concentration of Proinebrium is required to achieve 50% inhibition of ethylene glycol metabolism by alcohol dehydrogenase when the concentraion of ethlyene glycol in the blood is 50 uM?
While furthering your studies of iocane powder you determine that a ceular enzyme, iocase will degrade it. Under normal conditions, iocase shows km 0f 1.85 uM and a kcat of 76. The drug sildenafil was found to have no effect on the km of iocanse yet the kcat was found to drop 58 minutes^-1, when the drug was added and no other changes were made in the reaction conditions. What can be inferred from this data? (remember kcat = vmax/et) Sildenafil acts as an uncompetitive inhibitor of iocanse Sildenafil acts as a noncompetitive inhibitor of iocanse The effect of sildenafil could be countered by adding more iocane to the reaction The y-intercept of the sildenafil inhibited iocanse would appear to be lower on a Lineweaver burke plot as compared to uninhibited iocanase The slope of a Lineweaver burke plot of the inhibited versus uninhibited iocanase would remain unchanged

An experiment was carried out to measure the reaction rate of hydrolysis of acetylcholme (substrate) with serum enzymes (Eadie, 1949). In the experiment, two experiments were conducted, namely experiment 1 without using a prostigmine inhibitor and experiment 2 using a prostigmine inhibitor at 1.5 x 10^-7 mol/l. the data obtained are: a. Is prostigmine competitive or noncompetitive inhibitor? b. determine the value of km and rmax for the two experiments, compare

The inhibitory effect of an uncompetitive inhibitor is greater at high [S] thanat low [S]. Explain this observation.
A particular enzyme-catalyzed reaction has an apparent Vmax = 9.00 nmol s-1 and α' = 3.00 when 2.00 µmol L-1 inhibitor X is present and uncompetitively inhibiting the reaction. Calculate Vmax for the uninhibited reaction in nmol s-1.
