The study of protein-ligand interaction has been of a great interest in contemporary structural biology. The understanding of the nature of such interaction and determining the associated binding affinities are of utmost importance. NMR has become a powerful tool in deriving information related to such interactions in proteins. NMR data provides the site-specific information even in the case of proteins having multiple-binding sites and populations of respective species. In this communication, we set out to use such information to derive the associated microscopic binding constants.
