High-Resolution Solid-State NMR Applied to Polypeptides and Membrane Proteins

Solid-state NMR provides unique possibilities to study insoluble or noncrystalline molecules at the atomic level. High-resolution conditions can be established by employing magic-angle spinning at ultrahigh magnetic fields. We discuss NMR methods that make use of these experimental improvements and allow for the study of multiply or uniformly [¹³C,¹⁵N]-labeled polypeptides and proteins. Recent biophysical applications are reviewed.
