AFM images of the pRNA hexamer showing the structurally flexible arms to meet the sequential action requirement of each hexameric subunit to execute the revolving motion. (A, left) A model of the pRNA-triangle hexamer used for AFM imaging. (Right) An example of the full-sized AFM images. (B) Zoomed-in AFM images of the pRNA hexamer showing the flexible arms for cooperative inter-subunit shifting and revolving.
