Dominique, Marion

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 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...	nmrlearner	Journal club	0	11-17-2011 01:47 AM
