  ABSTRACT  
 
Aminoglycosides are widely used antibiotics that cause messenger RNA decoding errors, block mRNA and transfer RNA translocation, and inhibit ribosome recycling. Ribosome recycling follows the termination of protein synthesis and is aided by ribosome recycling factor (RRF) in bacteria. The molecular mechanism by which aminoglycosides inhibit ribosome recycling is unknown. Here we show in X-ray crystal structures of the Escherichia coli 70S ribosome that RRF binding causes RNA helix H69 of the large ribosomal subunit, which is crucial for subunit association, to swing away from the subunit interface. Aminoglycosides bind to H69 and completely restore the contacts between ribosomal subunits that are disrupted by RRF. These results provide a structural explanation for aminoglycoside inhibition of ribosome recycling.

Figure 1.
(a) Chemical structures of neomycin, paromomycin and gentamicin. (b) Global view of the ribosome and the two binding sites for aminoglycosides. Gold and green, aminoglycosides bound to the 30S and 50S subunits, respectively; light blue, 16S rRNA; gray, 23S rRNA; purple, 5S rRNA; dark blue and magenta, proteins of small and large subunits, respectively; CP, central protuberance. (c) Close-up view of the two binding sites in h44 and H69, shown with neomycin as an example. Neomycin molecules bound to h44 and H69 are in gold and green, respectively. Green, orange and blue shadows outline positions that would be occupied by mRNA, A-site tRNA and P-site tRNA, respectively. The mRNA and tRNAs are above the plane of the image. Inset shows direction of view.
Figure 3.
(a) F[o] – F[o] difference electron density map, truncated at 6-Å resolution, comparing 70S ribosome crystals in complex with RRF to ribosomes in complex with neomycin. In the absence of RRF, the overall position of H69 at the interface in apo–70S ribosomes is essentially identical to that in neomycin-bound ribosomes (Supplementary Methods). Only domain I of RRF is visible; domain II is located to the right of the view shown. Blue, positive difference density; red, negative difference density; arrow, direction of the conformational change in H69 upon RRF binding. (b) F[o] – F[o] difference electron density as in a, but at 3.5-Å resolution. Insets in a and b show angles of view.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
