CC -!- FUNCTION: Membrane-anchoring subunit of succinate dehydrogenase (SDH)
CC that is involved in system II of the mitochondrial electron transport
CC chain and is responsible for transferring electrons from succinate to
CC ubiquinone (coenzyme Q). SDH3 and SDH4 form the membrane dimer that
CC anchors the catalytic dimer formed by SDH1 and SDH2 to the matrix
CC surface of the mitochondrial inner membrane. Electrons originating from
CC the catalytic dimer enter the membrane dimer for ubiquinone reduction.
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle.
CC -!- SUBUNIT: Forms part of complex II containing four subunits: a
CC flavoprotein (FP), an iron-sulfur protein (IP) and a cytochrome b
CC composed of a large and a small subunit.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane
CC protein.
CC -!- MISCELLANEOUS: Present with 7920 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the CybS family. {ECO:0000305}.
