RESUMO
In one of the first steps of prokaryotic ribosome assembly, the ribosomal protein S15 binds to a three-way junction in the central domain of the 16S rRNA. Binding causes a conformational change that is required for subsequent binding events. Using a novel fluorescence resonance energy transfer assay with three fluorophores, two on the RNA and one on the S15 protein, small-molecule libraries can be screened for potential inhibitors of this initial step in ribosome assembly. The employment of three fluorophores allows both the conformational change of the RNA and the binding of S15 to be monitored in a single assay.
