Protein

Fumarate reductase flavoprotein subunit

Gene

SO_0970

Organism
Shewanella oneidensis (strain MR-1)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes fumarate reduction using artificial electron donors such as methyl viologen. The physiological reductant is unknown, but evidence indicates that flavocytochrome c participates in electron transfer from formate to fumarate and possibly also to trimethylamine oxide (TMAO). This enzyme is essentially unidirectional (By similarity).By similarity

Catalytic activityi

Succinate + a quinone = fumarate + a quinol.

Cofactori

FADNote: Binds 1 FAD per subunit.
