Plays an essential role in the assembly of succinate dehydrogenase (SDH, respiratory complex II), an enzyme complex that is a component of both the tricarboxylic acid cycle and the electron transport chain, and which couples the oxidation of succinate to fumarate with the reduction of ubiquinone (coenzyme Q) to ubiquinol. Required for flavinylation (covalent attachment of FAD) of the flavoprotein subunit SdhA of SDH (PubMed:22474332, PubMed:24374335, PubMed:26644464). Required for flavinylation of the flavoprotein subunit FrdA of fumarate reductase (FRD) (PubMed:26644464).
