== Publication Abstract from PubMed ==

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.

Crystal structure of the bacterial ribosome from Escherichia coli in complex with gentamicin and ribosome recycling factor (RRF). This file contains the 30S subunit of the first 70S ribosome, with gentamicin bound. The entire crystal structure contains two 70S ribosomes and is described in remark 400.
