Abstract

This proposal concerns a study of the dynamics and thermodynamics of the interaction of the major urinary protein (MUP) with a panel of pyrazine-derived ligands, using isothermal titration calorimetry (ITC), x-ray crystallography, NMR and computational methods. The aim of this work is to characterise not only the enthalpic component of binding, but also the entropic component of binding for each ligand arising from dynamics of the ligand, protein and solvent. Preliminary ITC data on the panel of chosen ligands indicate that entropy is the dominant driving force for binding, and show intriguing enthalpy-entropy compensation phenomena that we hope to delineate by exploiting the sensitivity of high-resolution NMR to conformational entropy.
