Abstract excerpt
Many viruses regulate protein synthesis by -1 ribosomal frameshifting using an RNA pseudoknot. Frameshifting is vital for viral reproduction. Using the information gained from the recent high-resolution crystal structure of the beet western yellow virus pseudoknot, a systematic mutational analysis has been carried out in vitro and in vivo. We find that specific nucleotide tertiary interactions at the junction...
