III, Redford P., Roesch P., RA Rasko D., Buckles E.L., Liou S.-R., Boutin A., Hackett J., Stroud D., RA Mayhew G.F., Rose D.J., Zhou S., Schwartz D.C., Perna N.T., RA Mobley H.L.T., Donnenberg M.S., Blattner F.R.; RT "Extensive mosaic structure revealed by the complete genome sequence RT of uropathogenic Escherichia coli."; RL Proc. Natl. Acad. Sci. U.S.A. 99:17020-17024(2002). 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 CC growth, and the succinate dehydrogenase is used in aerobic growth CC (By similarity). CC -!- CATALYTIC ACTIVITY: Succinate + acceptor = fumarate + reduced CC acceptor. CC -!- COFACTOR: Binds 1 2Fe-2S cluster (By similarity). CC -!- COFACTOR: Binds 1 3Fe-4S cluster (By similarity). CC -!- COFACTOR: Binds 1 4Fe-4S cluster (By similarity). CC -!- SUBUNIT: Fumarate dehydrogenase forms part of an enzyme complex CC containing four subunits: a flavoprotein, an iron-sulfur, and two CC hydrophobic anchor proteins (By similarity). CC -!- SIMILARITY: Belongs to the succinate dehydrogenase/fumarate CC reductase iron-sulfur protein family. CC -!- SIMILARITY: Contains 1 2Fe-2S ferredoxin-type domain. CC -!- SIMILARITY: Contains 1 4Fe-4S ferredoxin-type domain.
