The contents of this monograph represent the lectures at this Workshop. The unique and valuable information content of the NMR spectra of paramagnetic macromolecules has been recognized since the initial report on the spectrum of cytochrome c (A. Kowalsky (1965) Biochemistry, 4, 2382). However, the road to developing the methods for first detecting, then assigning the resonances of active site residues, and lastly interpreting the hyperfine shifts and relaxation in terms of molecular and electronic structure, has been a long and tortuous one. Nevertheless, the past decade has witnessed not only a strong resurgence in the interest in NMR of paramagnetic macromolecules, but also remarkable progress in the experimental methodology and understanding of the origins of the paramagnetically influenced spectral parameters. Hence the broad and in-depth potential of NMR studies on paramagnetic macromolecules has been clearly established. This workshop was organized to assess the current status of NMR studies of paramagnetic macromolecules with respect to the scope and limitations of the needed experimental approaches, the interpretive bases of the hyperfine shifts and relaxation for defining both molecular and electronic structure, and the range of systems which can be studied. The subject matter of the lectures, moreover, was not restricted to NMR studies, but included key contributions on the theoretical framework for interpreting NMR spectral parameters of spin-coupled chromophores, and computational approaches for modeling solution structure of macromolecules with paramagnetic centers. Two classes of systems have played a key role in the development of the field of NMR in paramagnetic macromolecules, heme proteins and iron-sulfur proteins. The unique role played by these two systems is due, in part, to their diverse function, structure and genetic origin, but largely because they contain well-defined chromophores, each of which can be studied in detail outside the protein matrix. These systems constitute the most successfully studied macromolecules, and a major portion (first eight and last six) of the seventeen contributions deal with heme and/or iron-sulfur proteins. The middle three chapters survey the progress on, and significant promise of, more difficult systems which do not possess a chromophore, but nevertheless have yielded remarkable insight into their structure in spite of the complexities. The Director is grateful to the members of the Organizing Committee, Ivana Bertini, Bernard Lamotte, Geoffrey R. Moore and Isabel Moura, for their contributions in planning the program, to Anjos L. Macedo for making all local arrangements in Sintra, and to Kendra L. Tanner for valuable and expert assistance in both organizing the Workshop and completing this monograph. Most importantly, the Director and Organizing Committee are indebted to the Scientific and Environmental Affairs Division of NATO, and to Alain Jubier, Director of the Supramolecular Chemistry Program, for the generous financial support of the Advanced Research Workshop.
