Protein

Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial

Gene

POPTR_0007s12750g

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

Functioni

Flavoprotein (FP) 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

FADUniRule 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_0001s36050g), Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (POPTR_0007s12750g), 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_0005s12530g), 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.
