A method is presented that dramatically improves the resolution of protein nuclear magnetic resonance (NMR) spectra by increasing their dimensionality to four. The power of this technique is demonstrated by the application of four-dimensional carbon-13--nitrogen-15 (13C-15N)--edited nuclear Overhauser effect (NOE) spectroscopy to interleukin-1 beta, a protein of 153 residues. The NOEs between NH and aliphatic protons are first spread out into a third dimension by the 15N chemical shift of the amide 15N atom and subsequently into a fourth dimension by the 13C chemical shift of the directly bonded 13C atoms. By this means ambiguities in the assignment of NOEs between NH and aliphatic protons that are still present in the three-dimensional 15N-edited NOE spectrum due to extensive chemical shift overlap and degeneracy of aliphatic resonances are completely removed. Consequently, many more approximate interproton distance restraints can be obtained from the NOE data than was heretofore possible, thereby expanding the horizons of three-dimensional structure determination by NMR to larger proteins.

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
Three-dimensional triple resonance experiments have become an integral part of virtually every solution NMR study of proteins. The approach relies on uniform isotopic enrichment of proteins with (13)C and (15)N, and establishes the scalar connectivity pathway between nuclei through the large (1)J(NH), (1)J(CH)(, 1)J(CC), and (1)J(CN)...

Three-dimensional triple resonance experiments have become an integral part of virtually every solution NMR study of proteins. The approach relies on uniform isotopic enrichment of proteins with 13C and 15N, and establishes the scalar connectivity pathway between nuclei through the large 1JNH, 1JCH, 1JCC, and 1JCN couplings. The magnetization transfer process takes place...
