The extended interface: measuring non-local effects in biomolecular interactions.
Improvements in the sensitivity and availability of biophysical techniques for the detection of the formation of complexes in solution are revealing that the effects of binding are not restricted to the direct contacts between the biomolecules or even to a localised site. Rather, information about the binding event is transmitted throughout the biomolecules and the surrounding solution through changes in the hydrogen bonding, hydration and electrostatic field as the complex is formed. Calorimetric, volumetric and NMR methods are beginning to provide a quantitative view of the nature and thermodynamic consequences of this extended interface, and the resulting data pose a major challenge for computational models of binding.
