Functioni

Iron-sulfur protein (IP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q).UniRule annotation

Catalytic activityi

Succinate + a quinone = fumarate + a quinol.UniRule annotation

Cofactori

Protein has several cofactor binding sites:
  • [2Fe-2S] clusterUniRule annotationNote: Binds 1 [2Fe-2S] cluster.UniRule annotation
