Function

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).

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
[2Fe-2S] cluster (UniProtKB | Rhea| CHEBI:190135 )

Note: Binds 1 [2Fe-2S] cluster.
[3Fe-4S] cluster (UniProtKB | Rhea| CHEBI:21137 )

Note: Binds 1 [3Fe-4S] cluster.
[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 1 [4Fe-4S] cluster.

Pathway

Carbohydrate metabolism; tricarboxylic acid cycle; fumarate from succinate (eukaryal route): step 1/1.
