a Subunits ND2, ND4 and ND5, showing the additional N-terminal TMHs in ND2, the β1-β2 and β3-β4 loops in ND4 and ND5 and the two bound Ca2+ ions. b The altered position of ND6-TMH4 and the C-terminal extension. c The C-terminus of Pd-NDUFV2 overlapping with bovine supernumerary subunit NDUFV3. d The different position of Pd-NDUFS2 N-terminus and the Ca2+ bound in Pd-NDUFS2. The Pd-CI structure was compared with the bovine active-apo state (no bound ligand) PDB-7QSL20.
