title: Competition between tetracycline and tRNA at both P and A sites of the ribosome of Escherichia coli.
abstract: Fluorescence anisotropy studies performed on 6-demethylchlortetracycline, binding to the ribosome of E. coli in competition with tRNA at the P site or at both P and A sites, have provided a quantitative assessment in situ of the interaction of this antibiotic with the A site and have demonstrated that there is also an interaction between tetracycline and the P site.
