Respiratory electron transport complexes are organized as individual entities or combined as large supercomplexes (SC). Gram-negative bacteria deploy a mitochondrial-like cytochrome (cyt) bc<sub>1</sub> (Complex III, CIII<sub>2</sub>), and may have specific cbb<sub>3</sub>-type cyt c oxidases (Complex IV, CIV) instead of the canonical aa<sub>3</sub>-type CIV. Electron transfer between these complexes is mediated by soluble (c<sub>2</sub>) and membrane-anchored (c<sub>y</sub>) cyts. Here, we repo  ...[more]
