A powerful method of sequential resonance assignment of protein 1H-NMR spectra is presented and illustrated with respect to the DNA-binding protein ner from phage Mu. It is based on correlating proton-proton through-space and through-bond connectivities with the chemical shift of the directly bonded 15N atom. By this means, ambiguities arising from chemical shift degeneracy of amide proton reso...

A theoretically consistent approach to the calculation of the Coulomb correlation corrections to the single–particle energies is presented. New contributions to the single–particle energies previously overlooked in the literature are now identified and taken into account. We show that the interplay between the Coulomb interaction and the strong interaction, which is enhanced in the nuclear surf...

DSHIFT is a web server for predicting chemical shifts of DNA sequences in random coil form or double helical B-form. The prediction methods are based on sets of published reference chemical shift values and correction factors which account for shielding or deshielding effects from neighboring nucleotides. Proton, carbon and phosphorus chemical shift predictions are available for random coil DNA...

A new 1D NMR experiment cited as 'Quick G-SERF', which re-introduces selective proton-proton scalar interactions in a pure shift spectrum during real time data acquisition, is reported. The method provides information on multiple proton-proton couplings from a single experiment, analogous to the 2D G-SERF technique, while significantly shortening the experimental time by 1-2 orders of magnitude...

Proton-detected 1H-13C heteronuclear correlated spectroscopy [( 1H,13C]-COSY) was used to establish relations between the carbon-13 and proton nuclear magnetic resonance chemical shifts in the hexadeoxynucleoside pentaphosphate d-(GCATGC)2. Using the previously established sequence-specific proton NMR assignments, sequence-specific assignments were thus obtained for nearly all proton-bearing ca...
