我们提出了一种3D 1h检测固态核磁共振(SSNMR)方法,用于10-100 nmol全质子化蛋白的主链信号分配,该方法使用超快速角旋转(MAS)在~80 kHz下使用一种新颖的光谱编辑方法,允许大幅简化光谱。该方法比传统的3D 13c检测SSNMR方法节省了约110倍的时间。
We present a 3D 1H-detected solid-state NMR (SSNMR) approach for main-chain signal assignments of 10–100 nmol of fully protonated proteins using ultra-fast magic-angle spinning (MAS) at ~80 kHz with a novel spectral-editing method, which permits drastic spectral simplification. The approach offers ~110 fold time saving over a traditional 3D 13C-detected SSNMR approach.
