NMR spectroscopy has proven to be a powerful technique to study the structure and dynamics of biological macromolecules. Fundamentals of Protein NMR Spectroscopy is a comprehensive textbook that guides the reader from a basic understanding of the phenomenological properties of magnetic resonance to the application and interpretation of modern multi-dimensional NMR experiments on 15 N/ 13 C-labeled proteins. Beginning with elementary quantum mechanics, a set of practical rules is presented and used to describe many commonly employed multi-dimensional, multi-nuclear NMR pulse sequences. A modular analysis of NMR pulse sequence building blocks also provides a basis for understanding and…

Professor of Biological Sciences at Carnegie Mellon University. Professor Rule's research is directed at understanding inter-molecular interactions in biological systems. An understanding of these interactions is required if biological systems are to be comprehended at the molecular level. The combined tools of molecular biology, NMR spectroscopy and x-ray crystallography are used to provide important information to aid in our understanding of these interactions. Our research efforts have been directed at enzyme-substrate interactions, protein-lipid interactions, antibody-antigen interactions, and protein-nucleic acid interactions
