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|RuleBase:RU361237}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a quinone + succinate = a quinol + fumarate;

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 four subunits: a
CC       flavoprotein (FP), an iron-sulfur protein (IP), and a cytochrome b
CC       composed of a large and a small subunit.
