A procedure is described that affords complete 1H, 13C and 15N resonance assignment in proteins of up to about 25 kDa. The new approach requires uniform isotopic enrichment of the protein with 13C and 15N and correlates resonances of adjacent nuclei using the relatively large and well-resolved one-bond J couplings. Spectral overlap, a common problem in the application of two-dimensional NMR, is removed by increasing the dimensionality of the new methods to three or four, without increasing the number of observed resonances. With complete 1H, 13C and 15N resonance assignments available, the nuclear Overhauser effect (NOE)-based interproton distance constraints can be extracted in a very straightforward manner from four-dimensional NOE spectra.

Application of iterative soft thresholding for fast reconstruction of NMR data non-uniformly sampled with multidimensional Poisson Gap scheduling
Abstract The fast Fourier transformation has been the gold standard for transforming data from time to frequency domain in many spectroscopic methods, including NMR. While reliable, it has as a drawback that it requires a grid of uniformly sampled data points. This needs very long measuring times for sampling in multidimensional experiments in all indirect dimensions uniformly and even does not allow reaching optimal evolution times that would...

Four new and complementary three-dimensional triple-resonance experiments are described for obtaining complete backboneH,C, andN resonance assignments of proteins uniformly enriched withC andN. The new methods all rely onH detection and use multiple magnetization transfers through well-resolved one-bondJcouplings. Therefore, the...

Abstract NMR spectroscopic characterization of the structure or the dynamics of proteins generally requires the production of samples isotopically enriched in 15N, 13C, or 2H. The bacterial expression systems currently in use to obtain isotopic enrichment, however, cannot produce a number of eukaryotic proteins, especially those that require post-translational modifications such as N-linked glycosylation for proper folding or activity. Here, we report the use of an...
