By implementing new NMR methods that were designed to map very slow exchange processes we have investigated and characterized the refolding kinetics of a thermodynamically stable 34mer RNA sequence in dynamic equilibrium. The RNA sequence was designed to u ...

Temperature-dependent protein backbone dynamics from auto- and cross-correlated NMR relaxation rates

Geoffrey Bodenhausen

The temp. dependence of NMR relaxation rates was investigated for the backbone of 15N/13C labeled human ubiquitin in the temp. range of 20-50 DegC. The 15N autorelaxation rates give evidence that the potential energy functions for 15N-HN bonds are not quad ...

High-resolution NMR spectroscopy in solids by truly magic-angle spinning

Geoffrey Bodenhausen

Right angles: In solid-state magic-angle spinning (MAS) NMR spectra, the line widths of carbonyl carbon atoms in polycryst. cholesteryl acetate are as narrow as 0.039 ppm if the magic angle is adjusted very accurately, i.e., within +-0.004 Deg. The line br ...

Determination of 13C CSA Tensors: Extension of the Model-independent Approach to an RNA Kissing Complex Undergoing Anisotropic Rotational Diffusion in Solution

Geoffrey Bodenhausen

Chem. shift anisotropy (CSA) tensor parameters have been detd. for the protonated carbons of the purine bases in an RNA kissing complex in soln. by extending the model-independent approach [Fushman, D., Cowburn, D. (1998) J. Am. Chem. Soc. 120, 7109-7110]. ...

Slow Diffusion by Singlet State NMR Spectroscopy

Geoffrey Bodenhausen, Simone Cavadini

Small diffusion coeffs. can be measured by using populations of singlet states that have a relaxation time const., Ts, which can be much longer than the longitudinal relaxation time, T1. Spatial information can be encoded with pulsed field gradients in the ...

QUADRUPOLAR NUCLEI NMR USING RESIDUAL DIPOLAR COUPLINGS

Geoffrey Bodenhausen

Method for obtaining two-dimensional nuclear magnetic resonance spectrum of quadrupolar nuclei of nitrogen-14, involves recording signal of neighboring nucleus with specific spin after specific duration ...

Anisotropic Local Motions and Location of Amide Protons in Proteins

Geoffrey Bodenhausen

A new method has been developed to obtain dynamic and structural information about peptide planes in proteins by a combination of measurements of weak short-range cross-correlation rates R(HNN/NC') that are due to concerted fluctuations of the HN-N and N-C ...
