Colour coding as in Extended Data Fig. 1: cyan (atenolol), blue (isoprenaline), orange (dobutamine), purple (alprenolol), red (carvedilol), green (cyanopindolol), black (apo receptor). For clarity the centres of resonances are marked by circles. Firmly (tentatively) assigned residues are marked in black (cyan).
