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;
