(5 points) What fraction of the protein is bound at ligand concentration of 1.25 µM (a WebAffinity: "Affinity" simply refers to how strong the binding is (as judged by Kassociation or Kdissociation and ∆Go). "High affinity" refers to very strong binding (large negative ∆Go and a very small K d). The association or dissociation constant is often referred to as the "affinity” or “binding” constant.
WebThe two ligands bindings can be described by A + R = AR and B + R-BR, respectively. If the binding affinity (K) is kwon for the ligand B, the binding affinity (Ka) for ligand A can be calculated with equation: [ARI/R:= [A] (KA1+ [B]/KB) + [A]).
