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...</br>
