Although biopolymers can act as protein ligands and are increasingly important therapeutic agents, the drug discovery aspects of their binding thermodynamics are less explored and are not considered here. 1 Basic Equations of Ligand–Protein Binding Thermodynamics The binding affinity of a ligand (L) to a protein (P) can be characterized by the dissociation constant, Kd: Kd ~ ½L½P ½LP ð2:1Þ corresponding to the process LP Thus, the ligand is treated quantum mechanically and is polarized by the point charges of the target protein, and the induced dipole at a given target atom is then reformulated as an induced charge in an iterative manner. The final set of polarized charges was evaluated for 12 protein–ligand systems. Although inclusion of polarization does not always led to the lowest energy pose having a lower rmsd, it was found that the polarized charges resulted in an increased cluster size and a concomitant decrease in the rmsd of the docked pose with regard to the crystallographic solution.
