a Electrostatic potential map of a single Mat (red: negatively charged; blue: positively charged). b Electrostatic potential map of the Mat-dimer inserted in the Coat shell (white transparent surface). c Locations of Stem-loops 79, 88, and 51 (the operator, underlined), and the first 75 nucleotides of the 5’ end in the virion. d, e Models and secondary structures of Stem-loops 88 (Panel d) and 79 (Panel e), which interact with outer and inner Mat, respectively. f The model and secondary structure of Stem-loop 51, which interacts with one Coat-dimer. The start codon AUG, −5, and −18 positions are colored and labeled. g The model and secondary structure of the first 75 nucleotides at the 5’ end of the gRNA, which interacts with three Coat-dimers.
