Fig. 5 — Predicted structures of ORF1a/ORF1b ribosomal frame-shift element (RFS) and RNA prseudoknot structure in the Yichang virus genome.

(a) The genomic nucleotide (middle) and amino acid sequences (lower) of ORF1a and ORF1b around their overlapping sites. (b) A conserved pseudoknot structure of RNA immediately downstream of slippery sequence (GGAUUUU) about 150nt which reduce ribosomal −1 frameshift (RFS) in 12 typical mesoniviruses.
