FIG 3.

(A) Ribbon diagram of the structure of the coat protein subunit of PMMoV MG-WT and the indicated coat protein mutants modeled upon the crystal structure of U2-TMGMV and indicating the position of the genomic RNA. Root mean square deviations computed for backbone atoms are indicated. (B and C) Molecular surface of a three-turn section of the nine virus particle coat protein subunits that integrate a core nonamer used to analyze protein-protein interactions. Panel B shows a left, side view, and panel C shows a right, top view.
