Protein

Fumarate reductase iron-sulfur subunit

Gene

frdB

Organism
Proteus vulgaris
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.

Catalytic activityi

Succinate + a quinone = fumarate + a quinol.

Cofactori

Protein has several cofactor binding sites:
