Protein
Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial
Gene
sdha, TNeu107a09.1
Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

Catalytic activityi

Succinate + a quinone = fumarate + a quinol.

Cofactori

FAD By similarity.
