Background information for motor pRNA, pRNA three-way junction (3WJ), and the application of their thermodynamic stability to build RNA nanoparticles. (A) The side-view of the hexametric structure of phi29 DNA packaging motor.79 Two bottom panels are side-view and top-view of the hexameric pRNA derived from X-ray crystallography.80 (B) Predicted secondary structure of the phi29 packaging RNA (pRNA) with the 3WJ motif outlined and the pRNA-3WJ and pRNA-3WJ secondary structure with solved crystal structure.
