Fig. 3: Parasite-specific subunits and resolved lipids at the dimer interface.

a Fo map cross-section showing apicomplexa-specific (purple) and conserved (light blue) subunits, as well as lipid vestibules (red, orange). The apicomplexa-specific subunits scaffold the Fo architecture. Close-up inset shows protein-cardiolipin (CDL) contact at dimer interface with subunits b and f interacting via a tightly bound cardiolipin. b IF1 dimer (green density) binds to Fo (dark grey density) and F1 of both monomers (transparent grey), linking them together. Close-up inset shows IF1 interactions with subunit-b (violet).
