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 ...

A refocused INEPT through-bond coherence transfer technique is demonstrated for NMR of rigid organic solids and is shown to provide a valuable building block for the development of NMR correlation experiments in biological solids. The use of efficient prot ...
The central region of the matrix protein p17 of HIV-1 is known to be essential during virus assembly. We substituted alanines for amino acid triplets in this region of p17 (amino acid residues 47 to 55: NPG LLE TSE). Introduction of the respective mutation ...
A new two-dimensional solid-state NMR experiment, which correlates slow and fast chemical shift anisotropy sideband patterns is proposed. The experiment, dubbed ROSES, is performed under fast magic-angle spinning and leads to an isotropic spectrum in the d ...
Water-protein interactions play a major role in protein folding, structure, and function, and solid-state NMR has recently been shown to be a powerful tool for the site-resolved observation of these interactions in solid proteins. In this article we report ...
NMR-microprobes based on solenoids and Helmholtz coils have been microfabricated and NMR-spectra of mammalian cells have successfully been taken. The microfabrication technology developed for these probes consists of three electroplated copper levels for l ...
We present the design, fabrication and test of high-Q factor radiofrequency planar microcoils for nuclear magnetic resonance (NMR) spectroscopy in small volume samples. The coils are fabricated on glass wafers using high-aspect ratio SU-8 photoepoxy and co ...
Coherent and dissipative phenomena induced by transient adsorption of xenon-131 on a glass surface were studied by NMR spectroscopy. The authors report the results of multiple-quantum filtered expts. over a range of temps., covering different relaxation re ...
Nuclear magnetic resonance spectroscopy (MRS) in low and medium magnetic fields yields well-resolved natural abundance proton and decoupled phosphorus spectra from small (1-10 cc) volumes of brain in vivo in minutes. With this tool, neurochemical research ...
