WebNational Center for Biotechnology Information WebJul 1, 2024 · Nuclear Magnetic Resonance (NMR) spectroscopy is one of the two primary experimental means of characterizing macromolecular structures, including protein structures. Structure determination by NMR spectroscopy has traditionally relied heavily on distance restraints derived from nuclear Overhauser effect (NOE) measurements. While …

WebApr 17, 2007 · Development of alignment media for accurate residual dipolar coupling (RDC) measurements from α-helical membrane proteins would enhance significantly the capability of solution NMR in structure determination of this important class of targets. ... All NMR experiments were performed on spectrometers (Bruker, Billerica, MA) equipped with ... WebResidual dipolar couplings (RDCs) are an efficient tool for the determination of the relative configuration of small organic molecules.1–5The use of RDCs has been boosted by the availability of weak aligning media compatible with standard organic solvents such as CDCl36–10or DMSO-d6,11–18and most other common NMR solvents.19–22While it is … shuckle strategy

As opposed to traditional NOE based NMR structure determinations, RDCs provide long distance structural information. It also provides information about the dynamics in molecules on time scales … See more The residual dipolar coupling between two spins in a molecule occurs if the molecules in solution exhibit a partial alignment leading to an incomplete averaging of spatially anisotropic dipolar couplings. Partial molecular … See more The secular dipolar coupling Hamiltonian of two spins, $${\displaystyle I}$$ and $${\displaystyle S,}$$ is given by: where See more • Magnetic dipole–dipole interaction • Residual chemical shift anisotropy (rCSA) • Solid-state nuclear magnetic resonance (ssNMR) See more NMR spectroscopy in partially oriented media was first discovered in 1963, and in a very fundamental paper Alfred Saupe was also able to present the essential theory to describe and understand the observable phenomena only one year later. After this initiation a flood of … See more Any RDC measurement in solution consists of two steps, aligning the molecules and NMR studies: Methods for aligning molecules For diamagnetic molecules at moderate field strengths, molecules have little preference in … See more Books: • Emsley, J.
