Extended Data Figure 1. Sequences and structures of RNAs.
Top left: Sequence and secondary structure of the complete TYMV TLS and the Upstream Pseudoknot Domain (UPD, green dashed box). The UPD is just upstream of the UUAG sequence that is important for stabilizing the L-shaped structure and the UPD is known to be able to pack against the TLS5,11. Interestingly, the stop codon for the Coat protein is within the UPD (magenta). To the right and below: Sequences and secondary structures of all additional RNAs used in ribosome binding assays or discussed in the text. Yellow highlights indicate the location of mutation.
