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}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
