A 1H-15N NMR study was performed on the GDP-bound form of a truncated human c-Ha-ras oncogene product (171 amino acid residues). Resonance cross peaks of the backbone amide 1H-15N nuclei of a uniformly 15N-labeled protein were observed with heteronuclear single-quantum coherence spectroscopy (HSQC). In order to resolve overlapping cross peaks, selective 15N-labeling of one or two types of amino acid residues (Ala, Arg, Asx, Glx, Gly, His, Ile, Leu, Lys, Met, Phe, Ser, Thr, Tyr and/or Val) was carried out using appropriate E. coli mutant strains. By this procedure, all the backbone 1H-15N cross peaks were classified into amino acid types.

Abstract Long-range structural information derived from paramagnetic relaxation enhancement observed in the presence of a paramagnetic nitroxide radical is highly useful for structural characterization of globular, modular and intrinsically disordered proteins, as well as proteinâ??protein and protein-DNA complexes. Here we characterized the conformation of a spin-label attached to the homodimeric protein CylR2 using a combination of X-ray crystallography, electron...

Optimizing 19F NMR protein spectroscopy by fractional biosynthetic labeling
Abstract In protein NMR experiments which employ nonnative labeling, incomplete enrichment is often associated with inhomogeneous line broadening due to the presence of multiple labeled species. We investigate the merits of fractional enrichment strategies using a monofluorinated phenylalanine species, where resolution is dramatically improved over that achieved by complete enrichment. In NMR studies of calmodulin, a 148 residue calcium binding protein, 19F and 1H-15N HSQC spectra reveal a significant extent of line broadening and the appearance of minor conformers in the presence of...

The 15N signal assignment of human lysozyme was carried out by using 1H-1H and 1H-15N two dimensional experiments. To solve the severe overlap problem of the NH signals, uniform labeling of the protein with 15N was introduced. The uniformly 15N labeled protein was prepared using a high-expression system of Saccharomyces cerevisiae. From the analyses of 1H and 15N NMR...
