摘要:

氢氘交换核磁共振(HDX-NMR)与氢氘交换质谱(HDX-MS)是研究蛋白质结构与动力学的关键技术,近年广泛应用于解析蛋白质构象变化.HDX-NMR通过检测交换后的核磁共振信号,提供单氨基酸分辨率的动态信息,适用于缓慢交换区域及长时间尺度构象变化研究.HDX-MS整合氢氘交换与高分辨率质谱优势,可在近生理条件下测定蛋白质溶液态结构,适用于大分子复合体、膜蛋白等复杂体系.相较于X射线晶体学、冷冻电镜等传统技术,HDX-MS以高灵敏度和低样品需求量见长,HDX-NMR则在位点分辨率与动力学分析上更优.随着技术与方法的持续优化,二者在蛋白质构象变化、药物筛选等领域应用前景日益广阔.本文综述其原理、流程及分析方法,比较异同,探讨互补性与整合应用,展望未来方向,为相关研究提供参考.

Abstract:

Hydrogen-deuterium exchange nuclear magnetic resonance (HDX-NMR) and hydrogen-deuterium exchange mass spectrometry (HDX-MS) are key techniques for studying protein structure and dynamics, and have been widely applied to analyzing protein conformational changes in recent years. HDX-NMR provides dynamic information at single amino acid resolution by detecting nuclear magnetic resonance signals after exchange, and is suitable for studying slow exchange regions and conformational changes over long time scales. HDX-MS integrates the advantages of hydrogen-deuterium exchange and high-resolution mass spectrometry, enabling the determination of protein solution structures under near-physiological conditions, and is applicable to complex systems such as macromolecular complexes and membrane proteins. Compared with traditional techniques like X-ray crystallography and cryo-electron microscopy, HDX-MS is characterized by high sensitivity and low sample demand, while HDX-NMR is superior in site resolution and kinetic analysis. Ongoing technological and methodological optimizations are further broadening the application prospects of both techniques in areas such as protein conformational changes and drug screening. This article reviews their principles, procedures, and analytical methods, compares their similarities and differences, discusses their complementarity and integrated applications, and outlines future directions, aiming to provide references for related research.
