Relationship between Affinity and Association & Dissociation Constant. Four proteins (A-D) all bind the same ligand (X), with different affinities. For protein A & B we know that they have a binding site for X with a Kd (dissociation constant) of 10-5and 10-8M, respectively. For protein C and D we know that they have a binding site for ligand X with a Ka (association constant) of 103and 105M, respectively. Which protein has the highest affinity for ligand X? Explain your reasoning.

How can distance validate non-covalent interactions? Also, please explain if the distance between c-alpha of a particular residue in an enzyme and c-alpha of its ligand are 12.4 Å, 11.7 Å, 6.5 Å, 7.6 Å, and 7.7 Å, what does that mean? What is the meaningful distance, what is the legth of hydrophobic,hydrophilic, h-bond...?

I did not understand soultion for the question.. The relationship between Affinity and Association & Dissociation Constant. Four proteins (A-D) all bind the same ligand (X), with different affinities. For protein A & B we know that they have a binding site for X with a Kd (dissociation constant) of 10⁻⁵and 10⁻⁸ M, respectively. For protein C and D we know that they have a binding site for ligand X with a Ka (association constant) of 10³and 10⁵M, respectively. Which protein has the highest affinity for ligand ? Explain your reasoning. How do you make them all in same constant so that values can be compared and the one with highest Ka or lowest Kd (Highest affinity in both cases) can be ruled out.
If the ligand-binding pocket is largely hydrophobic, what does this tell us about the energetics of binding compared to one that is lined with charged residues? What forces are directing ligand binding? Note: Please address everything mentioned above!.

Refer to the bar graph below, Explain why e.g. the n→π* interactions contribute more to the overall stabilization of the protein than all the other interactions(C-H-O hydrogen bond,π-π interactions, C5 Hydrogen Bonds, Cation-π interactions, Sulfur-arene interactions, Anion-π interactions, Chalcogen bonds, X-H-π interactions) even though n→π* is the weaker interaction. Explain why they contribute more than EACH bond.
A protein binds a ligand with a ka value of 7.4 x 104 M-1s-1 and a kd value of 6.4 x 10-4 s-1. What is the KD value of this binding event in units of nM? Please report your answer to two significant figures and include units.
Noncompetitive inhibition is a limiting case in which the effect of binding inhibitor has no effect on the affinity for the substrate and vice versa. Suggest what a Lineweaver– Burk plot would look like for an inhibitor that had a reaction scheme similar to the scheme below, but where binding inhibitor lowered the affinity of EI for the substrate.
