CC -!- FUNCTION: Flavoprotein (FP) subunit of succinate dehydrogenase (SDH)
CC that is involved in complex II of the mitochondrial electron transport
CC chain and is responsible for transferring electrons from succinate to
CC ubiquinone (coenzyme Q). {ECO:0000256|RuleBase:RU362051}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a quinone + succinate = a quinol + fumarate;
CC Xref=Rhea:RHEA:40523, ChEBI:CHEBI:24646, ChEBI:CHEBI:29806,
CC ChEBI:CHEBI:30031, ChEBI:CHEBI:132124; EC=1.3.5.1;
CC Evidence={ECO:0000256|RuleBase:RU362051};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|ARBA:ARBA00001974,
CC ECO:0000256|RuleBase:RU362051};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (eukaryal route): step 1/1.
CC {ECO:0000256|RuleBase:RU362051}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000256|RuleBase:RU362051}; Peripheral membrane protein
CC {ECO:0000256|RuleBase:RU362051}; Matrix side
CC {ECO:0000256|RuleBase:RU362051}.
CC -!- SIMILARITY: Belongs to the FAD-dependent oxidoreductase 2 family.
CC FRD/SDH subfamily. {ECO:0000256|ARBA:ARBA00008040,
CC ECO:0000256|RuleBase:RU362051}.
