Gene

SDH2-2

Organism
Arabidopsis lyrata subsp. lyrata (Lyre-leaved rock-cress)
Status

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

  • [4Fe-4S] clusterUniRule annotationNote: Binds 1 [4Fe-4S] cluster.UniRule annotation

Pathway:itricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes fumarate from succinate (eukaryal route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Succinate dehydrogenase [ubiquinone] iron-sulfur subunit, mitochondrial (SDH2-2), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (SDH1-2), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (SDH1-1), Succinate dehydrogenase [ubiquinone] iron-sulfur subunit, mitochondrial (SDH2-1)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.
