Here we report the 3.6 Å structure of the human AR in complex with adenosine and heterotrimeric G protein determined by Volta phase plate cryo-electron microscopy. Compared to inactive AR, there is contraction at the extracellular surface in the orthosteric binding site mediated via movement of transmembrane domains 1 and 2. At the intracellular surface, the G protein engages the AR primarily via amino acids in the C terminus of the Gα α5-helix, concomitant with a 10.5 Å outward movement of the AR transmembrane domain 6. Comparison with the agonist-bound β adrenergic receptor-G-protein complex reveals distinct orientations for each G-protein subtype upon engagement with its receptor. This active AR structure provides molecular insights into receptor and G-protein selectivity. | ||||||
