Abstract
Membrane proteins present a challenge for structural biology. In this article, we review some of the recent developments that advance the application of NMR to membrane proteins, with emphasis on structural studies in detergent-free, lipid bilayer samples that resemble the native environment. NMR spectroscopy is not only ideally suited for structure determination of membrane proteins in hydrated lipid bilayer membranes, but also highly complementary to the other principal techniques based on X-ray and electron diffraction. Recent advances in NMR instrumentation, spectroscopic methods, computational methods, and sample preparations are driving exciting new efforts in membrane protein structural biology.

Rotational-echo double-resonance (REDOR) solid-state NMR is applied to probe the membrane locations of specific residues of membrane proteins. Couplings are measured between protein 13CO nuclei and membrane lipid or cholesterol 2H and 31P nuclei. Specific 13CO labeling is used...

Recent advances in segmental isotope labeling of proteins: NMR applications to large proteins and glycoproteins
Abstract In the last 15 years substantial advances have been made to place isotope labels in native and glycosylated proteins for NMR studies and structure determination. Key developments include segmental isotope labeling using Native Chemical Ligation, Expressed Protein Ligation and Protein Trans-Splicing. These advances are pushing the size limit of NMR spectroscopy further making larger proteins accessible for this technique. It is just emerging that segmental isotope...

The fact that membrane proteins are notoriously difficult to analyse using standard protocols for atomic-resolution structure determination methods have motivated adaptation of these techniques to membrane protein studies as well as development of new technologies. With this motivation, liquid-state nuclear magnetic resonance...
