[NMR paper] Role of rotational motion in diffusion NMR experiments on supramolecular assemblies: application to Sup35NM fibrils
Role of rotational motion in diffusion NMR experiments on supramolecular assemblies: application to Sup35NM fibrils
Pulsed-field gradient (PFG) NMR is an important tool for characterization of biomolecules and supramolecular assemblies. However, for micron-sized objects, such as amyloid fibrils, these experiments become difficult to interpret because in addition to translational diffusion they are also sensitive to rotational diffusion. We have constructed a mathematical theory describing the outcome of PFG NMR experiments on rod-like fibrils. To test its validity, we have studied the...

In this paper, we discuss methods for determining structures of protein-ligand complexes by NMR in solution. Our discussion is based on small ligands (<2 kDa) as for example drugs, metabolites or oligo-peptides, but most of the considerations also apply to more general cases. In NMR in solution, the kinetics of association and dissociation of the complex – the exchange rate –...

The main drawback of protein NMR spectroscopy today is still the extensive amount of time required for solving a single structure. The main bottleneck in this respect is the manual evaluation of the experimental spectra. A clear solution to this challenge is the development of automated methods for this purpose. At the current stage of development, this goal has...

The introduction of nuclear magnetic resonance (NMR) spectroscopy as a second method for protein structure determination at atomic resolution, in addition to x-ray diffraction in single crystals, has already led to a significant increase in the number of known protein structures. The NMR method provides data that are in many ways...
