2JZZ - PubMed Abstract: 
Proton-driven 13C spin diffusion (PDSD) is a simple and robust two-dimensional NMR experiment. It leads to spectra with a high signal-to-noise ratio in which cross-peaks contain information about internuclear distances. We show that the total information content is sufficient to determine the atomic-resolution structure of a small protein from a single, uniformly 13C-, 15N-labeled microcrystalline sample. For the example of ubiquitin, the structure was determined by a manual procedure followed by an automatic optimization of the manual structure as well as by a fully automated structure determination approach. The relationship between internuclear distances and cross-peak intensities in the spectra is investigated.
