Overall fold of the RNA complexes. Structures of the RNA complex in space groups P6522 (a) and P212121 (b) are depicted in cartoon representation and coloured cyan and yellow for the WT strands and green and magenta for the 5nt strands. (c) RNA sequences showing the interactions between strands. Colours correspond to (a) and (b). Short and long bonds represent Watson and Crick and Hoogsteen base pairing, respectively. The grey adenosine is the intercalating A10. (d) Close-up view of an example of Watson and Crick and Hoogsteen base pairing.
