Cross section of the large subunit of the bacterial ribosome. In yellow - the exit tunnel of the proteins from the ribosome. In red - the binding pocket of erythromycin at the entrance to the tunnel. Bottom right (marked in light blue) – the ribosomal protein L22. In structural and chemical terms, the protein is distant from the binding pocket of the antibiotic.
