The ColE1 RNA kissing dimer. (A) Cartoon representation two RNAs resembling the ColE1 RNAs based on the NMR solution structure [14, 86]. Stemloops SL1 (green) and SL2 (blue) interact via a loop-loop kissing between SL1 loop residues (dark green) and SL2 residues (dark blue). (B) Secondary structure of the two RNAs with the seven base pairs between the two loops indicated.
