Protein

Succinate dehydrogenase flavoprotein subunit

Gene

sdhA

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
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.
