Protein
Succinate dehydrogenase flavoprotein subunit
Gene
sdhA, c0801
Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
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

FAD.
