WebAug 26, 2024 · Given the latest advances in the ability of cryo–electron microscopy (cryo-EM) to solve dynamic RNA-only structures ( 11 – 14 ), we reasoned that this technique may offer a way to directly observe the 3D structure of RNA folding intermediates, including misfolded states, which have been elusive to structural biology. WebCryoEM structures demonstrate that the splicing reaction is catalyzed by RNA with the help of two Mg 2+ ions. (a) The left panel is a model of the spliceosome (presumably the B* complex) immediately before the branching reaction, generated based on …
