The first part provides a basic understanding of the factors governing protein-ligand interaction, followed by a comparison of the four key experimental methods (calorimetry, surface plasmon resonance, NMR and X-ray crystallography) used in generating interaction data. The second half of the book is devoted to in-silico methods of modeling and predicting molecular recognition and binding. Here, as elsewhere in the book, emphasis is placed on novel approaches and recent improvements to established methods. The final part looks at unresolved challenges, and the strategies to address them Bibliography Includes bibliographical references and index Notes English Print version record Subject Proteins.
