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|ARBA:ARBA00001971};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle.
CC {ECO:0000256|ARBA:ARBA00005163}.
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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OUI89528.1}.
