ENZYME entry: EC 1.3.5.1

Accepted Name
Succinate dehydrogenase (quinone).
Alternative Name(s)
Succinate dehydrogenase (ubiquinone).
Succinic dehydrogenase.
Reaction catalysed
Succinate + a quinone <=> fumarate + a quinol
Cofactor(s)
FAD; Iron-sulfur.
Comment(s)
  • The enzyme is found in the inner mitochondrial membrane in eukaryotes and the plasma membrane of many aerobic or facultative bacteria.
  • It catalyzes succinate oxidation in the citric acid cycle and transfers the electrons to quinones in the membrane, thus constituting a part of the aerobic respiratory chain (known as complex II).
  • In vivo the enzyme uses the quinone found in the organism - eukaryotic enzymes utilize ubiquinone, bacterial enzymes utilize ubiquinone or menaquinone, and archaebacterial enzymes from the Sulfolobus genus use caldariellaquinone.
  • Cf. EC 1.3.5.4.
