(D)-(F) The models of the selected minimal structural ensembles (Ne=3) that can reproduce the scattering curves of the complete sfRNAs of DENV2 (D), ZIKV (E) and WNV (F) are shown. In each panel, the left are the three individual models in each ensemble overlaid on top of the DB1domains, the right are the three individual models in each ensemble displayed separately. The xrRNA1, xrRNA2, SL3 of WNV, ψ-DB1 and DB1, DB2, and 3'SL domains are colored in red, blue, cyan, green, magenta and orange, respectively.
