Fig. 1: Schematic view of electron and proton transfer by CIII2 and CIV.

Electron transfer between CIII2 and CIV is mediated via soluble cyt. c. Reactions catalyzed by one-half of the CIII2 homodimer and CIV are detailed. Quinol and quinone-binding sites are indicated as QP and QN, respectively. Dashed black arrows indicate electron transfer, while yellow arrows indicate proton-transfer reactions. IMS is intermembrane space.
