CC -!- FUNCTION: Membrane-anchoring subunit of succinate dehydrogenase (SDH).
CC {ECO:0000256|ARBA:ARBA00004050}.
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000256|PIRSR:PIRSR000178-1};
CC Note=The heme is bound between the two transmembrane subunits.
CC {ECO:0000256|PIRSR:PIRSR000178-1};
CC -!- SUBUNIT: Part of an enzyme complex containing four subunits: a
CC flavoprotein, an iron-sulfur protein, plus two membrane-anchoring
CC proteins, SdhC and SdhD. The complex can form homotrimers.
CC {ECO:0000256|ARBA:ARBA00025912}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the cytochrome b560 family.
CC {ECO:0000256|ARBA:ARBA00007244}.
