When three-dimensional NMR spectra are presented as two stereoscopic images, they create a convincing three-dimensional impression for the viewer. In an extension of this principle, we record plane projections of a three-dimensional spectrum at different angles, and use this limited information to reconstruct the entire spectrum. Projections onto different skew planes are derived by Fourier transformation of signals acquired while the two evolution parameters are incremented simultaneously at different rates. By limiting the amount of data gathering, this offers an appreciable economy of instrument time. Normally two to six different projections suffice, depending on the complexity of the spectra. There is an order-of-magnitude speed advantage over the conventional methodology, where both evolution dimensions must be explored independently. Results are presented for reconstructed HNCA and HN(CO)CA spectra of ubiquitin and the HNCO spectrum of a 187-residue protein HasA.

We demonstrate that two projection experiments, aN-HSQC–NOESY–N-HSQC and aC-HSQC–NOESY–N-HSQC, recorded for a histone domain from yeast, contain enough information to support a structural characterisation of the protein. At the temperature used, 298K, the histone domain exhibits a very high extent of chemical shift degeneracy that is uncharacteristic for...

Ambiguities in two-dimensional nuclear magnetic resonance spectra due to overlap are usually resolved by recording a three-dimensional version of the experiment. It is shown that a simpler solution is to record a tilted projection of the three-dimensional spectrum, derived by Fourier transformation of the...

Recording of four-dimensional (4D) spectra for proteins in the solid state has opened new avenues to obtain virtually complete resonance assignments and three-dimensional (3D) structures of proteins. As in solution state NMR, the sampling of three indirect dimensions leads per se to long minimal measurement time. Furthermore,...
