摘要: Rotational echo double resonance (REDOR) is a solid-state NMR technique that provides direct measure of heteronuclear dipolar coupling typically between isolated pairs labeled nuclei under magic angle spinning conditions. The couplings contain information on both distance and orientation; therefore REDOR can serve as spectroscopic ruler protractor in the study molecular systems. In addition, it be used selection tool to filter spectra based couplings. Over past 20 years, has been employed around world obtain site-specific atomic-level metabolic pathways, protein-ligand interactions, analysis noncrystalline, poorly soluble heterogeneous systems such synthetic polymers, membrane proteins, intact plant leaves, bacterial cells cell walls. this review, we provide survey recent applications illustrate problem-solving versatility biological systems.
