Cover Picture: Proton‐Detected Solid‐State NMR Spectroscopy of Fibrillar and Membrane Proteins (Angew. Chem. Int. Ed. 19/2011)

Solid‐state NMR spectroscopyhas recently emerged as a tool for structural biology. Sensitivity and resolution, however, still hamper more widespread applications. Protons are ideal as they have the largest gyromagnetic ratio, but they can induce severe line broadening. As described in the Communication by B. Reif and co‐workers on page 4508 ff.,perdeuteration and partial back‐substitution of exchangeable protons can overcome the strong coupling problem. The approach is successfully implemented for fibrils and membrane proteins.
