- ProteinSuccinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial
- StatusUniProtKB unreviewed (TrEMBL)
- Amino acids609 (go to sequence)
- Protein existenceInferred from homology
- Annotation score3/5
Function
function
Flavoprotein (FP) 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
- a quinone + succinate = fumarate + a quinol
Cofactor
Pathway
Carbohydrate metabolism; tricarboxylic acid cycle; fumarate from succinate (eukaryal route): step 1/1.
