enzyme operates with both natural quinones, ubiquinone and menaquinone, at a single quinone binding site. Residue Lys228 in subunit FrdB provides a strong hydrogen bond to menaquinone and is essential for reactions with both quinone types. There is similar hydrogen bonding of the C1 carbonyl of both MQ and UQ, whereas there is different hydrogen bonding for their C4 carbonyls

succinate + phenazine methosulfate + 2,6-dichlorophenolindophenol
quinone reduction by Rhodothermus marinus succinate:menaquinone oxidoreductase is not stimulated by the membrane potential

succinate + a menaquinone
the enzyme is involved in anaerobic respiration with fumarate as the terminal electron acceptor, and is part of an electron transport chain catalysing the oxidation of various donor substrates by fumarate
