A scientist is trying to explain the free energy of binding (ΔGbind) between a ligand and protein receptor. Experimental measurements indicate a binding enthalpy of ΔHbind = -59.7 kcal/mol. After analyzing the crystal structure of the receptor-ligand complex, the scientist identifies three interface charge-charge contacts and reasons that all other energetic contributions can be ignored. The three charge-charge contacts have the following properties, Contact 1 involves a pair of positively (+1.0) and negatively (-1.0) charged atoms separated by 4.0 Å...
