FAD | ubiquinone reduction by an electron transfer relay comprising a flavin adenine dinucleotide cofactor, three iron-sulfur clusters, and possibly a heme b556. At the heart of the electron transport chain is a [4Fe-4S] cluster with a low midpoint potential that acts as an energy barrier against electron transfer | Escherichia coli | |
