| Accepted name: |

| Reaction: |
succinate + ubiquinone = fumarate + ubiquinol |

| Other name(s): |
succinic dehydrogenase; complex II; menaquinol: fumarate oxidoreductase; fumarate reductase complex (i.e. FRD, involved in anaerobic respiration, repressed in aerobic respiration); succinate dehydrogenase complex (i. e. SDH, involved in aerobic respiration, repressed in anaerobic respiration) |
| Systematic name: |
succinate:ubiquinone oxidoreductase |
| Comments: |
A flavoprotein (FAD) containing iron-sulfur centres. The complex, present in mitochondria, can be degraded to form EC 1.3.99.1 succinate dehydrogenase, which no longer reacts with ubiquinone. |
