(a) The VS ribozyme intermolecular substrate. The residues involved in a kissing interaction with stem–loop V of the ribozyme are shown with black circles. (b) The rearranged or ‘shifted’ structure of the VS ribozyme substrate. (c) The trans-cleaving VS ribozyme used in this study. Lower case nucleotides represent nucleotides added to facilitate transcription. Helix Ia is formed by base pairing of residues C619, G618 and U617 of the trans-cleaving substrate with G640, C641 and G642 of the ribozyme.
