Figure 1. — Predicted secondary structures of ø29 pRNA and model RNAs. (A) The 120-nt form of wild-type pRNA. The shaded residues in the CE-loop and the D-loop are considered to form intermolecular base pairs. (B) The 19-mer that contains the D-loop and the D-helix. The G–U base pair at the end of the D-helix was changed to G–C, and an additional G–C base pair added in order to stabilize the helix. (C) The 35-mer that contains a part of the C-helix, the CE-loop, the E-helix and the E-loop. A G–C base pair was added at the end of the C-helix in order to stabilize the helix, and the U-bulge in the C-helix has been removed. (D) 35 -uucg in which the UUCG tetraloop (colored in red) is substituted for the E-loop (bases 20–25).
