SHAPE analysis of the complete sfRNAs of WNV (E). Nucleotides with SHAPE reactivity greater than 0.85 are labeled in red, and moderately reactive site (0.4-0.85) are labeled in cyan. Unlabeled sites have low or no SHAPE reactivity (<0.4). The SHAPE reactivity were also annotated onto the corresponding secondary structures in (C). Nucleotides which SHAPE reactivity was not determined are labeled in gray in (C).
