最近,15 N检测的多维NMR实验已被引入用于蛋白质的研究。在15 N-TROSY实验中利用氮核的缓慢横向弛豫,即使在没有氘化的情况下,也可以记录高分子量蛋白质的高质量光谱。在这里,我们证明了三个15 N-检测的H-N相关实验(TROSY,BEST-TROSY和HSQC)的RNA的适用性。用最新建立的15 N-检测的BEST-TROSY实验记录了5个RNA分子(分子量为5 - 100 kDa)的光谱,该实验被证明是最灵敏的15 N-检测的H-N相关实验。这些光谱在15 N-维度上产生了高分辨率,即使对于较大的RNA,因为线宽随分子量的增加在1H-维度上比在15 N-维度上更明显。此外,我们可以通过实验验证Au和GC碱基对中亚氨基基团弛豫行为的差异。此外,我们表明,15 N-检测实验理论上应该受益于灵敏度和分辨率的优势,在较高的静态领域,但后者是模糊的交换动态内的RNA。
Recently,15N-detected multidimensional NMR experiments have been introduced for the investigation of proteins. Utilization of the slow transverse relaxation of nitrogen nuclei in a15N-TROSY experiment allowed recording of high quality spectra for high molecular weight proteins, even in the absence of deuteration. Here, we demonstrate the applicability of three15N-detected H–N correlation experiments (TROSY, BEST-TROSY and HSQC) to RNA. With the newly established15N-detected BEST-TROSY experiment, which proves to be the most sensitive15N-detected H–N correlation experiment, spectra for five RNA molecules ranging in size from 5 to 100 kDa were recorded. These spectra yielded high resolution in the15N-dimension even for larger RNAs since the increase in line width with molecular weight is more pronounced in the1H- than in the15N-dimension. Further, we could experimentally validate the difference in relaxation behavior of imino groups in AU and GC base pairs. Additionally, we showed that15N-detected experiments theoretically should benefit from sensitivity and resolution advantages at higher static fields but that the latter is obscured by exchange dynamics within the RNAs.
