Electron transfer in CDH from the substrate to various terminal electron acceptors. One- and two-electron acceptors (EA) can be reduced directly by the FADH2 in the DHCDH. Alternatively, electrons can be transferred by IET to the haem b in the CYTCDH, which works as a relay for the reduction of macromolocular electron acceptors like PMO, cyt c or an electrode
