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:0000256|ARBA:ARBA00002787,
CC ECO:0000256|RuleBase:RU361237}.
CC -!- CATALYTIC ACTIVITY:

CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000256|RuleBase:RU361237};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; fumarate
CC from succinate (eukaryal route): step 1/1.
CC {ECO:0000256|ARBA:ARBA00004788, ECO:0000256|RuleBase:RU361237}.
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:0000256|ARBA:ARBA00011313}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000256|ARBA:ARBA00004443, ECO:0000256|RuleBase:RU361237};
