Answer #1

As we know, Binding Affinity = Constant/ rate constant for backwards reaction

for the above table Binding Affinity will be 0.6/(2-1) = 0.6

1.5/(4-1) = 0.5

3.0/(6-1) = 0.6

6.0/(8-1) = 0.86

15.0/(10-1) = 1.67

    You have ligand that you know binds to your receptor, since you’ve measured its affinity using isothermal titration calorimetry. You want to know the exact pose of the ligand in its binding pocket, so you use a computer simulation to dock it to the receptor structure. Surprisingly, your software shows the ligand on the protein surface, not in the pocket at all. What type of experiment could you do to confirm the location of the binding site and pose of...

    Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
