要完全理解将蛋白质的结构无序状态连接到有序的生化功能状态的折叠过程,需要对中间结构状态进行详细表征,并具有高分辨率和位点特异性。虽然展开和部分折叠状态的内在不均匀性和动态性质限制了传统X射线衍射和溶液NMR在结构研究中的功效,但应用于冷冻溶液的固态NMR方法可以避免由于分子运动和构象交换而在展开和部分折叠状态中遇到的复杂性。此外,固态NMR方法可以在特定位点水平上提供定性和定量的结构信息,即使在存在结构不均匀性的情况下。本文综述了相关的固体核磁共振方法及其在蛋白质折叠研究中的初步应用。使用化学变性,以准备未折叠的状态在平衡或快速冷冻装置,以捕获非平衡,瞬态结构状态的亚毫秒的时间尺度上,最近的结果表明,固态NMR可以贡献重要的信息折叠过程中,是不是从更熟悉的生物物理方法。
Complete understanding of the folding process that connects a structurally disordered state of a protein to an ordered, biochemically functional state requires detailed characterization of intermediate structural states with high resolution and site specificity. While the intrinsically inhomogeneous and dynamic nature of unfolded and partially folded states limits the efficacy of traditional x-ray diffraction and solution NMR in structural studies, solid state NMR methods applied to frozen solutions can circumvent the complications due to molecular motions and conformational exchange encountered in unfolded and partially folded states. Moreover, solid state NMR methods can provide both qualitative and quantitative structural information at the site-specific level, even in the presence of structural inhomogeneity. This article reviews relevant solid state NMR methods and their initial applications to protein folding studies. Using either chemical denaturation to prepare unfolded states at equilibrium or a rapid freezing apparatus to trap non-equilibrium, transient structural states on a sub-millisecond time scale, recent results demonstrate that solid state NMR can contribute essential information about folding processes that is not available from more familiar biophysical methods.
