Protein

Fumarate reductase iron-sulfur subunit

Gene

frdB

Organism
Shigella flexneri
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

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

Binds 1 2Fe-2S cluster.By similarity
Binds 1 3Fe-4S cluster.By similarity
