CC   -!- FUNCTION: Membrane-anchoring subunit of succinate dehydrogenase (SDH).
CC       {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC       Note=The heme is bound between the two transmembrane subunits.
CC       {ECO:0000250};
CC   -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle.
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 (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the cytochrome b560 family. {ECO:0000305}.
