Residues in bold are part of the RT binding pocket extracted from the rhodopsin structure (PDB ID: 1U19). The Ballesteros-Weinstein numbering (superscript) is given for comparison with other GPCRs. Only long-range edges are reported i.e. the edges formed with neighboring residues (8 amino acids on either side) are filtered out.
