1 H Nuclear magnetic resonance (NMR) relaxometry was exploited to investigate the dynamics of solid proteins. The relaxation experiments were performed at 37 °C over a broad frequency range, from approximately 10 kHz to 40 MHz. Two relaxation contributions to the overall 1 H spin–lattice relaxation were revealed; they were associated with 1 H– 1 H and 1 H– 14 N magnetic dipole–dipole Cited by: 1.

High resolution X-ray crystallographic analysis and 31 P-nuclear magnetic resonance studies of the lipovitellogenin complex show that β-sheets of vitellogenin surround a cavity believed to be filled with lipid .
It has been proposed that as more lipid is added, the cavity expands by movement of the β-sheets. Apo B might associate with.

Many peptides and proteins are attached to or immersed in a biological membrane. In order to understand their function not only the structure but also their topology in the membrane is important. Solution NMR spectroscopy is one of the most often used approaches to determine the orientation and localization of membrane-bound peptides and proteins.

NOVEMBER 8, –JANU BY JIRI JONAS AND CHARLES P. SLICHTER. HERBERT SANDER GUTOWSKY and his students and collaborators made fundamental, pioneering discoveries in nuclear magnetic resonance (NMR). Their discoveries firmly established NMR as a major experimental tool in chemistry.
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong static magnetic field are perturbed by a weak oscillating magnetic field and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei.

Individual proteins and protein complexes, if not the whole phage particle, can be crystallized and the structure of such proteins solved by X-ray analysis.
Alternatively, protein structures can be solved by nuclear magnetic resonance (NMR) if high enough concentrations can be by: Thermal syntheses of polypeptides fail, however, for at least four reasons.
First, studies using nuclear magnetic resonance (NMR) have shown that thermal proteinoids "have scarce resemblance to natural peptidic material because beta, gamma, and epsilon peptide bonds largely predominate over alpha-peptide bonds." 4 1.

Magnetic resonance imaging (MRI) is a diagnostic and research procedure that uses high magnetic fields and radio-frequency signals to produce images.
The most abundant molecular species in biological tissues is water. However, slower techniques, such as nuclear magnetic resonance (NMR) (Fung and McGaughy, ), electron paramagnetic resonance (EPR) (Belagyi, ) (see Chapter 4), fluorescence polarization (Knight and Wiggins, ) and freezing behaviour (Rustgi et al., ), showed a restricted motion of at least a portion of cell water/5.
Kurt Wuthrich Â¨ Â¨ Eidgenossische Technische Hochschule, Zurich, Switzerland Â¨ INTRODUCTION My ï¬ rst job in the ï¬ eld of NMR with biological macromolecules started on October 1,when I joined the Biophysics Department at Bell Telephone Laboratories in Murray Hill, NJ.
The department was headed by Dr. Robert G. Shulman, whose NMR credentials at the time included solid. Nuclear Magnetic Resonance NMR is a versatile spectroscopy method for studying proteins (71) that, importantly, does not require crystallization and is well suited to the study of IDPs (34).
For a structured protein, the individual resonance peaks tend to be spread out (e.g., there is a large chemical shift dispersion) because the local. In Escherichia coli, proteins found in the periplasm or the outer membrane are exported from the cytoplasm by the general secretory, Sec, system before they acquire stably folded structure.
This dynamic process involves intricate interactions among cytoplasmic and membrane proteins, both peripheral and integral, as well as lipids. In vivo, both ATP hydrolysis and proton motive force are Cited by: Although it is topologically linear, in physiological conditions it folds into a unique (though flexible) three-dimensional structure.

Urey himself was concerned with the safety of nuclear power and the need for a national plan to dispose of nuclear wastes. He feared that the global expansion of nuclear generating facilities could cause the spread of nuclear weapons.
