An enzyme catalyzes the reaction M↽−−⇀N .
An enzyme catalyzes the reaction M = N. The enzyme is present at a concentration of 3.5 nM, and the Vmax is 1.9 uM -. The Km for substrate M is 2.9 uM. Calculate kcat kcat = 542.86 What values of Vmax and Km would be observed in the presence of sufficient amounts of an uncompetitive inhibitor to generate an a' of 1.5? apparent Vmax = 0.526 UM s-1 apparent Km = 1.2

You are still interested in the enzyme happyase, which catalyzes the following reaction: HAPPY = SAD Previously, you determined that kcat = 400 s and Km = 10 M for your sample of happyase. Further research shows that this happyase sample was actually contaminated with a reversible inhibitor called ANGER. When ANGER is fully removed from the happyase preparation and [Eltotalis 4 nM, the measured Vmax is increased to 4.8 umes-1 and the measured Km is now 15 MM. Use...

The following observations come from Lineweaver-Burke plots, based on kinetic data generated from a Michaelis/Menton-type enzyme (E) that catalyzes the hydrolysis of a peptide substrate (S). All data were generated in the presence of 18.0 μM total enzyme. The enzyme-catalyzed reaction has a Km of 3.00 μM and a Vmax of 2.00 μM/sec. The enzyme-catalyzed reaction in the presence of 15.0 μM of Inhibitor A has an apparent Km of 2.25 μM and an apparent Vmax of 1.50 μM/sec. The...
