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