Antibiotic selectivity for prokaryotic vs. eukaryotic decoding sites

Chem Commun (Camb). 2010 Aug 14;46(30):5542-4. doi: 10.1039/c0cc00423e. Epub 2010 May 13.

Abstract

A FRET assembly reports antibiotic affinities to two different RNA targets. A binder was labeled with a fluorophore that acts both as an acceptor for the emissive nucleoside on the bacterial A-site and a donor fluorophore for the terminally-labeled human A-site. Unlabeled drugs were used to dissociate the labeled antibiotic.
