Application of the Boundary Element Method to two Dimensional Dynamic Problems of Saturated Porous Media

Three-dimensional dimer structure of the lambda-Cro repressor in solution as determined by heteronuclear multidimensional NMR.

The 1H, 15N and 13C magnetic resonances of the lambda-Cro repressor have been assigned almost completely, mainly through the use of heteronuclear multidimensional NMR methods. Inter-subunit NOEs were distinguished by means of heteronuclear spectral editing technique (13C double half filter technique). Based on the distance and dihedral angle constraints derived from the NMR data, the three-dime...

Assignment of the 31P and 1H resonances in oligonucleotides by two-dimensional NMR spectroscopy.

The use of new 1H-detected heteronuclear 1H-31P shift correlation experiments is demonstrated for oligonucleotides of 12 and 40 base pairs. The methods give unambiguous assignments of the 31P resonances and also permit identification of the C4' and C5' sugar protons. Use of the new methods enables one to make sequence-specific resonance assignments without reference to a known or assumed confor...

Study of phospholipid structure by 1H, 13C, and 31P dipolar couplings from two-dimensional NMR.

Various motionally averaged 31P-1H, 13C-1H, 1H-1H, and 31P-13C dipolar couplings were measured for natural-abundance and unoriented phosphocholine in the L alpha phase. The couplings were obtained and assigned by a variety of advanced and partly novel two-dimensional solid-state NMR experiments. Whereas 31P-1H and 31P-13C dipolar couplings provide long-range structural constraints, geminal 1H-1...
