Analytical expressions are derived for the analysis of the accuracy of NMR determinations of conformational equilibrium constants, K. The relative error, 蟽K/K, shows a nearly linear increase with K for two commonly used modifications of the NMR approach to conformational analysis (based on ...
An easy way to include weak alignment constraints into NMR structure calculations The algorithm is used for the structure refinement of the HIV-1 Nef protein using 252 dipolar coupling restraints. The approach is compared to the ... Hans-Jürgen,Sass,Giovanna,... - 《Journal of Biomolecular Nm...
The first Nuclear Magnetic Resonance (NMR) beams were detected in the 1930s by a team of researchers from Columbia University in New York City. Click to read more...
By nuclear magnetic resonance (NMR) analysis, we fi nd that the stoichiometry of polycrystalline DAST fi lms is 95% pure (limited by instrumental sensitivity). Using X-ray diff raction and other analytical techniques, we observe a signifi cant dependence of fi lm quality, such as ordering ...
Question: How do you distinguish R and S configuration from a chiral center? Chiral centre: Chiral centre or chiral carbon can be defined as that carbon centre which is connected to four different moieties or groups so that the molecule's mirror image is non-superimposable on itself. The ...

Cryo-EM does not require crystals and allows scientists to observe biomolecules moving and functioning, which is much harder to do with crystallography.NMR can also reveal very detailed structures but is restricted to relatively small proteins, or parts of them, including soluble, intracellular ...
