NMR spectroscopy is the most versatile technique for the investigation of structural and dynamic aspects of biological molecules and their interactions in solution. In addition, recent advances in the NMR instrumentation and methodology have allowed to overcome problems relating to macromolecule size and have made NMR a very feasible technique also for the investigation of highly dynamic, partially inhomogeneous molecules and heterogeneous complexes.

NMR has been widely employed to study molecular interactions that take place between biomacromolecules and their ligands at different levels of complexity. The characterization of the fine structural details of the recognition processes is essential to understand fundamental mechanisms underlying phenomena of biological and biomedical relevance and can be exploited for the rational design of new therapeutic and diagnostic strategies. In fact, ligands can be represented both by macromolecules, such as other proteins, nucleic acids or lipids, and small molecules (MW less than 1000 kDa), such as allosteric effectors, cofactors, substrates and their analogues, drugs.

Depending on the complex features, the interaction strength and the chemical nature of the interacting species, different experimental approaches can be chosen.

In this chapter we will describe the most important NMR techniques developed to study molecular recognition processes involving proteins and nucleic acids also focusing on their application to drug discovery and development. The most significant examples provided in literature will be also reported in details.
