Images showing the cryo-EM structures of KOR in complex with (a) Gαi1βγ (PDB: 8DzP), (b) αoAβγ PDB: 8DZQ), (c) αzβγ (PDB: 8DZQ) and (d) Gαgustducinβγ (PDB: 8DZR). (e) Image of all four structures superimposed, showing only the receptor and Gα subunits, colour-coded. (f) All four Gα subunits superimposed, highlighting the different positioning of the GαN helix.
These structures and observations were first published in Han et al. [127].
