The map is the result of combining multiple datasets: cryo-EM imaging of the beta-2AR-Gs + GTP (5 sec) complex was performed on a Titan Krios electron microscope equipped with a K3 Summit direct electron detector (Gatan). The microscope was operated at 300 kV accelerating voltage, with a nominal magnification of 105,000x in counting mode resulting in a magnified pixel size of 0.8677 Angstrom. A total exposure of 60.48 electrons/ Angstrom^2 over 63 frames with defocus ranging from -1.0 - -2.0 micrometers was used. Cryo-EM imaging of beta-2AR-Gs + GTP (10 sec) complex was performed on four separate grids over three collection sessions. The microscope was operated at 300 kV accelerating voltage, with a magnification at the camera of 58,679x in counting mode resulting in a magnified pixel size of 0.8521 Angstrom. For the first and second grids, movies were obtained at an exposure rate of 21.13 electrons/Angstrum^2/sec with defocus ranging from -0.4 - -2.0 micrometers. The total exposure time was 2.717 sec over 77 frames per movie stack. For an additional collection of the first grid, movies were obtained at an exposure rate of 20.95 electrons/ Angstrum^2/sec with defocus ranging from -0.4 -2.0 micrometers. The total exposure time was 2.717 sec over 77 frames per movie stack. For the third and fourth grids, movies were obtained at an exposure rate of 30.71 electrons/ Angstrum^2/sec with defocus ranging from -0.5 - -1.6 micrometers. The total exposure time was 2.008 sec over 79 frames per movie stack. Cryo-EM imaging of beta-2AR-Gs + GTP (17 sec) was performed on a Titan Krios equipped with a post-column energy filter, with a magnification of 105,000x in counting mode resulting in a magnified pixel size of 0.8677 Angstrom. Movies were obtained at an exposure rate of 32.46 electrons/Angstrum^2/sec with defocus ranging from -0.4 - -0.9 micrometers. The total exposure time was 1.999 sec over 79 frames per movie stack.
