Resonance assignment of intrinsically disordered proteins is made difficult by the extensive spectral overlaps. High-resolution 3D and 4D spectra are thus essential for this purpose. We have adapted the series of 3D BEST experiments proposed by Lescop et al [J. Magn. Reson. 187 (2007) 163–9] to the case of unfolded proteins. Longer acquisitions in the indirect dimensions are obtained by implementing semi-constant time evolution and sparse sampling. Using Maximum Entropy reconstruction for the indirect dimensions, the artifact intensity due to sparse sampling can be reduced to a level similar to the other sources of noise. The reduction of the sampled...

Al NMR: a novel NMR data processing program optimized for sparse sampling
Abstract Sparse sampling in biomolecular multidimensional NMR offers increased acquisition speed and resolution and, if appropriate conditions are met, an increase in sensitivity. Sparse sampling of indirectly detected time domains combined with the direct truly multidimensional Fourier transform has elicited particular attention because of the ability to generate a final spectrum amenable to traditional analysis techniques. A number of sparse sampling schemes have been described including radial sampling, random...

The development of non-uniform sampling (NUS) strategies permits to obtain high-dimensional spectra with increased resolution in significantly reduced experimental time. We extended a previously proposed signal separation algorithm (SSA) to process sparse four-dimensional NMR data. It is employed for two experiments...

One of the goals of structural genomics is to use three-dimensional structures to gain insights into the function of poorly understood or hypothetical proteins. Approximate functions are often apparent from the protein fold, but more...

Three-dimensional HNCO and HNCA subspectra from a small protein (agitoxin, 4 kDa, enriched in carbon-13 and nitrogen-15), have been obtained by direct frequency-domain excitation of selected carbon and nitrogen sites. This new technique applies an array of several simultaneous soft radiofrequency spin-inversion pulses, encoded (on or off) according to nested Hadamard matrices, and the...

Combining NMR and EPR Methods for Homodimer Protein Structure Determination
There is a general need to develop more powerful and more robust methods for structural characterization of homodimers, homo-oligomers, and multiprotein complexes using solution-state NMR methods. In recent years, there has been increasing emphasis on integrating distinct and complementary methodologies for structure determination of multiprotein ...
