Protein

Succinate dehydrogenase [ubiquinone] iron-sulfur subunit, mitochondrial

Gene

POPTR_001G338400v3

Organism
Populus trichocarpa (Western balsam poplar) (Populus balsamifera subsp. trichocarpa)
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

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

Pathwayi: tricarboxylic 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 (POPTR_001G338400v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_007G026400v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_007G026400v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_005G123900v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_007G026400v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_007G026400v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_005G123900v3), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_007G026400v3)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.
