Sustained effort has resulted in an impressive arsenal of tools for determining the static structures. But under physiological conditions, macromolecules undergo continuous conformational changes, a subset of which are functionally important. Techniques for capturing the continuous conformational changes underlying function are essential for further progress. Here, we present chemically-detailed conformational movies of biological function, extracted data-analytically from experimental single-particle cryo-electron microscopy (cryo-EM) snapshots of ryanodine receptor type 1 (RyR1), a calcium-activated calcium channel engaged in the binding of ligands. The functional motions differ substantially from those inferred from static structures in the nature of conformationally active structural domains, the sequence and extent of conformational motions, and the way allosteric signals are transduced within and between domains. Our approach highlights the importance of combining experiment, advanced data analysis, and molecular simulations. #1: ジャーナル: Nat Commun / 年: 2020 タイトル: Functional Pathways of Biomolecules Retrieved from Single-particle Snapshots 著者: Dashti, A. / des Georges, A. / Singharoy, A. / Frank, J. / Ourmazd, A. | |||||||||||||||||||||||||||

Author stated the following: At the current resolution filter and threshold, the core of the channel is well resolved and the model fits well the density of that region, but more external and lower resolution regions are more scattered and don't fit well with the model. Because our analysis focuses on the higher-resolution central region, we have chosen the 0.16 threshold most appropriate for this region. 対称性のタイプ: POINT | ||||||||||||
