High-resolution membrane protein structure by joint calculations with solid-state NMR and X-ray experimental data
High-resolution membrane protein structure by joint calculations with solid-state NMR and X-ray experimental data
Abstract X-ray diffraction and nuclear magnetic resonance spectroscopy (NMR) are the staple methods for revealing atomic structures of proteins. Since crystals of biomolecular assemblies and membrane proteins often diffract weakly and such large systems encroach upon the molecular tumbling limit of solution NMR, new methods are essential to extend structures of such systems to high resolution. Here we present a method that incorporates solid-state NMR restraints alongside...
