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:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a quinone + succinate = a quinol + fumarate;
CC Xref=Rhea:RHEA:40523, ChEBI:CHEBI:24646, ChEBI:CHEBI:29806,
CC ChEBI:CHEBI:30031, ChEBI:CHEBI:132124; EC=1.3.5.1;
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Note=Binds 1 [2Fe-2S] cluster.;
CC -!- COFACTOR:
CC Name=[3Fe-4S] cluster; Xref=ChEBI:CHEBI:21137;
CC Note=Binds 1 [3Fe-4S] cluster.;
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Note=Binds 1 [4Fe-4S] cluster.;
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (bacterial route): step 1/1.
CC -!- SUBUNIT: Part of an enzyme complex containing four subunits: a
CC flavoprotein, an iron-sulfur, cytochrome b-556, and a hydrophobic
CC anchor protein. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the succinate dehydrogenase/fumarate reductase
CC iron-sulfur protein family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL19679.1; Type=Erroneous initiation; Evidence={ECO:0000305};
