| Definition | The P-site of the ribosome binds the peptidyl-tRNA with the growing polypeptide chain, and is a common target for many antibiotics that inhibit the 50S ribosomal subunit. Some antibiotics (oxazolidinones) block the 50S subunit from interacting with the 30S subunit to prevent the formation of the ribosomal complex. Other antibiotics (thiostrepton) block the 50S subunit from interacting with elongation factors G and Tu (EF-G, Ef-Tu), preventing GTP-dependent reactions of peptidyl transferase, and translocation, respectively. Other antibiotics (macrolides) prevent protein translocation. |
