PSs encode critical features of viral CPs involved in PS RNA recognition. (A) View of the contacts between the ordered portion of the B3 RNA (cf. PS3) and the PS3-encoded amino acids (space filling representation) in the B3 VLP structure (PDB ID 4BCU). (B) The MS2 coat protein dimer in A/B conformation in complex with the highest affinity genomic PS, the TR stem-loop (34). The amino acids in the A (blue) and B (green) chains that are encoded by one of the four PSs within the CP gene (Fig. S7) are shown in space-filling representation.
