Zusammenfassung:Fluorescence polarization has been used recently to monitor diverse macromolecular interactions. In this report, the application of fluorescence polarization has been extended to monitor ribozyme reactions in real time. With fluorescently labeled substrate RNAs, group I ribozyme ligation and hammerhead ribozyme cleavage reactions were studied by fluorescence polarization in substrate excess (multiple turnover) conditions. These results also show that fluorescently labeled RNAs remain active substrates for ribozymes. Furthermore, a direct comparison of fluorescence polarization with fluorescence resonance energy transfer showed that both techniques were comparable for monitoring ribozyme reactions.
