Figure 8.

Schematic interaction map summarizing the major non-Watson–Crick hydrogen bonds and stacking interactions between selected bases and 6′ group of aminoglycosides in (A) the free riboswitch, (B) complex with NEO, (C) complex with PAR. The width of red and blue lines indicates the percentage of simulation frames in which these interactions were present. For clarity, the interactions observed in <10% of frames and the stable stacking between G5 and G9 in all simulations are omitted. High Na+ density and uridine shift are symbolically marked in relevant panels.
