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 -!- FUNCTION: Iron-sulfur protein (IP) subunit of the succinate
CC dehydrogenase complex (mitochondrial respiratory chain complex II),
