Fig. 1

a 3D reconstruction of HiSiaQM in complex with Mb3 in lipid nanodiscs (contour level 0.384). A map of the nanodisc was overlayed in transparent grey to show the relative position of the lipid bilayer. Selected secondary structure elements are indicated. The individual domains and their color code are identified in panel (b). b Topology diagram of HiSiaQM. c Cartoon representation of HiSiaQM with the same color scheme as in (a) and (b). Secondary structure elements are indicated.
