    Functioni

    Two distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth.By similarity

    Catalytic activityi

    Succinate + a quinone = fumarate + a quinol.

    Cofactori

    FAD.
