What factors affect binding affinity? Correct Answer-Shape, charge, H-bonding, hydrophobics reversible binding Correct Answer-the association of a protein with its ligan is concentration-dependent K_d Correct Answer-the concentration of ligand at which 1/2 of the protein is ligand-bound K_d = k_d / k_a or k_off / k_on also = k_-1 / k_1 Calculate fraction of protein bound to ligand Correct Answer-[L] / ([L] + K_d) affinity and concentration association Correct Answer-if they bind at...
