Abstract:
The discovery and design of biologically important RNA molecules has typically outpaced three-dimensional structural characterization. This talk will describe Ribosolve, a hybrid method integrating cryo-EM. biochemistry, and computer modeling, and its application to conserved segments of the SARS-CoV-2 RNA genome. The virus's frameshifting element is the smallest macromolecule (88 nt; 28 kDa) resolved by single-particle cryo-EM at subnanometer resolution to date and illustrates how rapid structure determination can lead to functional insights with implications for biomedical targeting of RNA.
