Pseudoknot length modulates the folding, conformational dynamics, and robustness of Xrn1 resistance of flaviviral xrRNAs

Exoribonuclease-resistant RNAs (xrRNAs) are RNA elements that block the exoribonucleolytic degradation of RNA. Here the authors show how a long-range pseudoknot length modulates the Mg2+-dependence of flaviviral xrRNA’s folding, conformational dynamics and Xrn1 resistance.
