CC -!- FUNCTION: Iron-sulfur protein (IP) subunit of succinate dehydrogenase
CC (SDH) that is involved in complex II of the mitochondrial electron
CC transport chain and is responsible for transferring electrons from
CC succinate to ubiquinone (coenzyme Q). {ECO:0000250}.
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 -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135; Evidence={ECO:0000250};
CC Note=Binds 1 [2Fe-2S] cluster. {ECO:0000250};
CC -!- COFACTOR:
CC Name=[3Fe-4S] cluster; Xref=ChEBI:CHEBI:21137; Evidence={ECO:0000250};
CC Note=Binds 1 [3Fe-4S] cluster. {ECO:0000250};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000250};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (eukaryal route): step 1/1.
CC -!- SUBUNIT: Component of complex II composed of four subunits: a
CC flavoprotein (FP), an iron-sulfur protein (IP), and a cytochrome b
CC composed of a large and a small subunit. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Matrix side {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the succinate dehydrogenase/fumarate reductase
CC iron-sulfur protein family. {ECO:0000305}.
