Comments

| Function | Recognizes and binds in the vacant E-site of ribosomes stalled by some peptidyltransferase center (PTC)-targeting antibiotics. Makes contact with the PTC and both ribosomal subunits. Induces conformational changes in the P-site, which allows it to dislodge the antibiotic from its PTC binding site. |
| Subunit | Binds within the E-site of the 70S ribosome, where it contacts ribosomal proteins of the large and small subunit, the 16 and 23S rRNAs and the acceptor arm of the P-site tRNA. |
| Subcellular location | Cytoplasm. Note=Does not stably associate with ribosomes. |
| Domain | The antibiotic resistance domain (ARD) is packed between the 23S rRNA and the acceptor arm of the P-site tRNA and inserts into the peptidyltransferase center (PTC). The C-terminal extension (CTE) contacts the small ribosomal subunit, positioned in the Shine-Dalgarno-anti-Shine-Dalgarno cavity. |
| Similarity | Belongs to the ABC transporter superfamily. ABCF family. ARE2 subfamily. |
