2023年9月27日 · Previously unrecognized structural signatures of RNA secondary and tertiary structures are identified through wide-angle solution scattering experiments. With millisecond time resolution, we observe an RNA fold from a dynamically varying single strand through a base-paired intermediate to assume a triple-helix conformation.

NMR可以看到蛋白的动力学，但只能看小蛋白。 2. EM电镜能看很大的蛋白复合物，但是看不了小蛋白，而且（2013年以前）分辨率低，看不太清楚。 3. X-ray晶体结构解析最牛，大小都能 …

In this chapter, we present applications of FTIR for the structural analysis of RNA, including the analysis of helical parameters and noncanonical base pairing, often found in RNA. The effect of temperature pretreatment, which has a great impact on RNA folding, will also be discussed.

Currently, X-ray diffraction analysis (XRD) with high spatial and time resolution (TR-XRD) is based on the known theory of X-ray scattering, where the main parameter of USP—its duration—is not taken into account.

2022年12月6日 · Currently, X-ray diffraction analysis (XRD) with high spatial and time resolution (TR-XRD) is based on the known theory of X-ray scattering, where the main parameter of USP-its duration-is not taken into account. In the present work, it is shown that, for scattering of attosecond USPs on DNA and RNA …

X-ray crystallography represents the most widely used technique to characterize RNA-protein complexes at atomic resolution; however, determining their three-dimensional structures remains challenging.
