title: Study on structure of ribosomal RNA by time-resolved luminescence anisotropy analysis.
abstract: Evaluation of the folded structure of E.coli 16S-rRNA was performed using 5'-Ru(II) complex labeled oligodeoxyribonucleotide (Ru-probe) as the probe. This probe could evaluate the dynamic manner of the binding site of Ru-probe by using the time-resolved luminescence anisotropy technique. It was found that the rotational manner of Ru-probe in the presence of 16S-rRNA was markedly dependent on the oligonucleotide sequence, indicating that the microenvironments around the Ru-probes were largely different.
