Obtaining unambiguous resonance assignments remains a major bottleneck in solid-state NMR studies of protein structure and dynamics. Particularly for supramolecular assemblies with large subunits (>150 residues), the analysis of crowded spectral data presents a challenge, even if three-dimensional (3D) spectra are used. Here, we present a proton-detected 4D solid-state NMR assignment procedure that is tailored for large assemblies. The key to recording 4D spectra with three indirect carbon or nitrogen dimensions with their inherently large chemical shift dispersion lies in the use of sparse non-uniform sampling (as low as 2%). As a proof-of-principle we acquired 4D (H)COCANH, (H)CACONH and (H)CBCANH spectra of the 20 kDa bacteriophage tail tube protein gp17.1 in a total time of two and a half weeks. These spectra were sufficient to obtain complete resonance assignments in a straightforward manner without use of previous solution NMR data.

PhD students and postdocs in ultra fast-MAS proton-detected solid-state NMR
The group of Prof. Dr. Rasmus Linser at the Ludwig-Maximilians-University in Munich, Germany, is looking for additional group members in the field of ultra fast-MAS bio-NMR.
Our focus is the characterization of protein structure, dynamics and interactions, using both solution and solid-state NMR spectroscopy. In the past, we have committed ourselves to the development of innovative NMR methodology as well as application of new and...

Towards automatic protein backbone assignment using proton-detected 4D solid-state NMR data
Towards automatic protein backbone assignment using proton-detected 4D solid-state NMR data
Abstract
We introduce an efficient approach for sequential protein backbone assignment based on two complementary proton-detected 4D solid-state NMR experiments that correlate \( {\text{H}}_{{\text{i}}}^{{\text{N}}} \) /Ni with CAi/COi or CAiâ??1/COiâ??1. The resulting 4D spectra exhibit excellent sensitivity and resolution and are amenable to (semi-)automatic assignment...
