Abstract
A procedure based on multiple quantum two-dimensional nuclear magnetic resonance spectroscopy is described for generation of 1H--15N chemical shift correlation maps. The method is used to obtain 15N chemical shifts for the exchangeable imino protons in 1H--15N units of site-specifically labeled Escherichia coli tRNAMetf in water. The high sensitivity and excellent chemical shift dispersion of the multiple quantum two-dimensional technique make it ideally suited for studying protonated nitrogens by NMR.
摘要
描述了一种基于多量子二维核磁共振波谱的方法，用于生成1H-15N化学位移相关图谱。该方法用于在水中对位点特异性标记的大肠杆菌甲硫氨酸转运核糖核酸（tRNAMetf）的1H-15N单元中可交换亚氨基质子获取15N化学位移。多量子二维技术的高灵敏度和出色的化学位移分散性使其非常适合通过核磁共振研究质子化氮。
