Solid-state NMR studies of proteins: the view from static 2H NMR experiments

The application of solid-state 2H NMR spectroscopy to the study of protein and peptide structure and dynamics is reviewed. The advantages of solid-state NMR for the study of proteins are considered, and the particular advantages of solid-state 2H NMR are summarized. Examples of work on the integral membrane protein bacteriorhodopsin, and the membrane peptide gramicidin, are used to highlight the major achievements of the 2H NMR technique. These examples demonstrate that through the use of oriented samples, it is possible to obtain both structural and dynamic information simultaneously.Key words: solid-state NMR, 2H NMR, membrane peptides, membrane proteins, oriented bilayers.
