This chapter describes nuclear magnetic resonance (NMR) methods that can be used to determine the structures of protein complexes. Many of these techniques are also applicable to other systems (e.g., protein-nucleic acid complexes). In the first section, we discuss methodologies for optimizing the sample conditions for the study of complexes. This is followed by a description of the methods that can be used to map interfaces when a full structure determination of the complex is not appropriate or not possible. We then describe experimental approaches for resonance assignment in complexes, these are essentially the same as those for isolated proteins. Subheading 6. describes the different types of so-called X-filtered NMR experiments that have been devised to separate and selectively observe either inter- or intramolecular structural information. These filtered NMR experiments are then exploited in the experimental strategies for structure determination of either protein complexes or homodimeric proteins. This is followed by a description of the calculation of their structures. Finally, we present case studies from three projects carried out in our laboratory, where we successfully used the methods presented in this chapter.

Structure determination of protein?RNA complexes in solution provides unique insights into factors that are involved in protein/RNA recognition. Here, we review the methodology used in our laboratory to overcome the challenges of protein?RNA structure determination by nuclear magnetic resonance (NMR). We use as two examples complexes recently...

PCS-based structure determination of proteinâ??protein complexes
Abstract A simple and fast nuclear magnetic resonance method for docking proteins using pseudo-contact shift (PCS) and 1HN/15N chemical shift perturbation is presented. PCS is induced by a paramagnetic lanthanide ion that is attached to a target protein using a lanthanide binding peptide tag anchored at two points. PCS provides long-range (~40 Ã?) distance and angular restraints between the lanthanide ion and the observed nuclei, while the 1HN/15N chemical shift perturbation data provide loose contact-surface information. The usefulness of this method was demonstrated through the structure...

Introduction
As the structures of more proteins and domains are solved by structural genomics projects, the future of structural biology will be oriented more toward the study of macromolecular complexes. Since so many biological processes are mediated by interactions between proteins, it is important to study them at a molecular level. The study of protein-protein interactions also has applications in a...

Abstract:
Rational drug design depends on the knowledge of the three-dimensional (3D) structure of complexes between proteins and lead compounds of low molecular weight. A novel nuclear magnetic resonance (NMR) spectroscopy strategy based on the paramagnetic effects from lanthanide ions allows the rapid determination of the 3D structure of a small...
