CC -!- FUNCTION: Two distinct, membrane-bound, FAD-containing enzymes are
CC responsible for the catalysis of fumarate and succinate
CC interconversion; the fumarate reductase is used in anaerobic growth,
CC and the succinate dehydrogenase is used in aerobic growth.
CC {ECO:0000256|ARBA:ARBA00002054}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a quinone + succinate = a quinol + fumarate;
CC Xref=Rhea:RHEA:40523, ChEBI:CHEBI:24646, ChEBI:CHEBI:29806,

CC ECO:0000256|PIRSR:PIRSR630664-51, ECO:0000256|RuleBase:RU362051};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (bacterial route): step 1/1.
CC {ECO:0000256|ARBA:ARBA00004894, ECO:0000256|RuleBase:RU362051}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000256|ARBA:ARBA00004515, ECO:0000256|RuleBase:RU362051};
CC Peripheral membrane protein {ECO:0000256|ARBA:ARBA00004515,

CC Membrane {ECO:0000256|ARBA:ARBA00004287}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004287}; Cytoplasmic side
CC {ECO:0000256|ARBA:ARBA00004287}.
CC -!- SIMILARITY: Belongs to the FAD-dependent oxidoreductase 2 family.
CC FRD/SDH subfamily. {ECO:0000256|ARBA:ARBA00008040,
CC ECO:0000256|RuleBase:RU362051}.
