Backbone Assignment of Fully Protonated Solid Proteins by ~1H Detection and Ultrafast Magic-Angle-Spinning NMR Spectroscopy

摘要

In the past decade solid-state magic-angle-spinning (MAS) NMR spectroscopy has emerged as a unique technique for obtaining information on the atomic-level structure and dynamics of complex biological macromolecules, which owing to their properties or size are accessible neither to X-ray crystallography nor to solution NMR spectroscopy. A small number of structures has been determined by solid-state NMR spectroscopy to date, ranging from microcrystalline samples to fibrils and membrane-associated systems. Despite rapid acceptance in the biomolecular field, however, these determinations are far from being routine.
