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:0000250|UniProtKB:P31040}.
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:0000250|UniProtKB:P31040};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000250|UniProtKB:Q0QF01};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (eukaryal route): step 1/1.
CC {ECO:0000250|UniProtKB:P31040}.
CC -!- SUBUNIT: Component of complex II composed of eight subunits in plants:
CC four classical SDH subunits SDH1, SDH2, SDH3 and SDH4 (a flavoprotein
CC (FP), an iron-sulfur protein (IP), and a cytochrome b composed of a
CC large and a small subunit.), as well as four subunits unknown in
CC mitochondria from bacteria and heterotrophic eukaryotes.
CC {ECO:0000269|PubMed:15604729}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:14671022, ECO:0000305|PubMed:25732537}; Peripheral
CC membrane protein {ECO:0000269|PubMed:14671022}; Matrix side
CC {ECO:0000269|PubMed:14671022}.
CC -!- TISSUE SPECIFICITY: Ubiquitous. Preferentially expressed in flowers and
CC inflorescences. {ECO:0000269|PubMed:12374303}.
CC -!- SIMILARITY: Belongs to the FAD-dependent oxidoreductase 2 family.
CC FRD/SDH subfamily. {ECO:0000305}.
