Comments

FUNCTION: Iron-sulfur protein (IP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) (By similarity).
CATALYTIC ACTIVITY: Succinate + ubiquinone = fumarate + ubiquinol.
COFACTOR: Binds 1 2Fe-2S cluster (By similarity).
COFACTOR: Binds 1 3Fe-4S cluster (By similarity).
COFACTOR: Binds 1 4Fe-4S cluster (By similarity).
PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle .
SUBUNIT: Component of complex II composed of four subunits: the flavoprotein (FP) SDHA, iron-sulfur protein (IP) SDHB, and a cytochrome b composed of a large and a small subunit (By similarity).
SUBCELLULAR LOCATION: Mitochondrion inner membrane; Peripheral membrane protein; Matrix side (By similarity).
DEVELOPMENTAL STAGE: Expressed during seed development. Detected during seed maturation and decreased during germination.
SIMILARITY: Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
SIMILARITY: Contains 1 2Fe-2S ferredoxin-type domain.
SIMILARITY: Contains 1 4Fe-4S ferredoxin-type domain.
