Primary and secondary structures of SLI and SLV RNAs used in this study. (A) The SLIps substrate RNA and related variants. SLIpsΔIa and SLIsbΔIa are derivatives of SLIps and SLIsb, respectively, in which stem Ia is absent (boxed region). SLIsd2 is a G5A variant of SLIds1. The VS ribozyme cleavage site for SLIps, SLIpsΔIa, SLIsb, and SLIsbΔIa is between residues −1 and +1 of SLI. (B) The wild-type SLV RNA and related SLV variants. In A and B, residues that participate in the three W-C base pairs at the I/V kissing-loop junction are shaded in gray.
