General annotation (Comments)
| 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) By similarity. |
| Catalytic activity | Succinate + ubiquinone = fumarate + ubiquinol. |
| Cofactor | FAD By similarity. |
| Pathway | |
| Subunit structure | Component of complex II composed of four subunits: a flavoprotein (FP), an iron-sulfur protein (IP), and a cytochrome b composed of a large and a small subunit By similarity. |
| Subcellular location | Mitochondrion inner membrane; Peripheral membrane protein; Matrix side. Ref.6 |
| Tissue specificity | Ubiquitous. Preferentially expressed in flowers and inflorescences. Ref.5 |
| Sequence similarities | Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily. |
