Here, hypothesizing that such differences in signalling efficacy might be captured structurally in intermediate states under non-equilibrium conditions, we use a time-resolved cryo-electron-microscopy approach to visualize the GTP-induced activation of the Gαβγ heterotrimer by the μ-opioid receptor bound to three ligands that show partial, full or super agonism on the receptor. We resolve ensembles of conformational states along the G-protein activation pathway, including an intermediate state that enables us to visualize receptor dynamics as a function of bound ligand. The results reveal ligand-dependent differences in state occupancy and conformational stability, with higher ligand efficacy correlating with increased dynamics of the receptor's transmembrane helices 5 and 6. Furthermore, we identify key differences between G and G in the mechanism of GTP-induced activation, which are likely to underlie the distinct activation kinetics of these G-protein types. Corroborated by molecular-dynamics simulations and single-molecule fluorescence assays, our findings provide a dynamic structural landscape of GPCR-G-protein interactions for ligands of various efficacies, and suggest that partial agonists produce a 'kinetic trap' during G-protein activation. | |||||||||
