Transition-state schematic and activity profiles for adenosine and N1-deazaadenosine at positions 9 and 10. (A) Transition-state stabilization of small ribozymes. (B) Single-turnover cleavage of adenosine and N1dA at position 9 and 10 of the HPRZ crystallization construct (Figure S1). The reaction was monitored for 4 h. Inset: bases at 9 and 10 of this investigation.
