ACIII–caa3 supercomplex. a Cryo-EM map of ACIII–caa3 supercomplex at 20 Å resolution. b Fit of ACIII model (this work) and Thermus thermophilus caa3 oxygen reductase (PDB 2YEV)32 to the ACIII–caa3 supercomplex map. c Fitted models without cryo-EM map. The relative position of ActE and subunit IIc from the caa3 oxygen reductase in the supercomplex is favorable for direct electron transfer between the two complexes (black arrow)
