摘要

我们在固态核磁共振（NMR）中提出了160 kHz的超快魔角旋转（MAS），在生物分子系统的质子检测实验中展示了前所未有的光谱质量和相干寿命。通过优化实验和样品条件以及利用先进的填充和处理工具，我们在微晶和膜重构蛋白上实现了卓越的分辨率，为结构生物学的新应用铺平了道路。

Pushing the Boundaries of Resolution in Solid-State Nuclear Magnetic Resonance of Biomolecules with 160 kHz Magic-Angle Spinning

We present ultrafast magic-angle spinning (MAS) at 160 kHz in solid-state nuclear magnetic resonance (NMR), demonstrating unprecedented spectral quality and coherence lifetimes in proton-detected experiments on biomolecular systems. By optimizing experimental and sample conditions and utilizing advanced filling and handling tools, we achieve superior resolution on both microcrystalline and membrane-reconstituted proteins, paving the way for new applications in structural biology.
