FunctionIron-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)
PathwayCarbohydrate metabolism; tricarboxylic acid cycle; fumarate from succinate (eukaryal route): step 1/1.
SimilarityBelongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family
SimilarityContains 1 2Fe-2S ferredoxin-type domain
SimilarityContains 1 4Fe-4S ferredoxin-type domain
Subcellular LocationMitochondrion inner membrane ; Peripheral membrane protein ; Matrix side .
SubunitComponent of complex II composed of four subunits: the flavoprotein (FP) SDHA, iron-sulfur protein (IP) SDHB, and a cytochrome b560 composed of SDHC and SDHD
