ENZYME entry: EC

Accepted Name
2-oxuglutarate dioxygenase (ethene-forming).
Alternative Name(s)
Ethylene-forming enzyme.
Reaction catalysed
2-oxoglutarate + O(2) <=> ethylene + 3 CO(2) + H(2)O
  • This is one of two simultaneous reactions catalyzed by the enzyme, which is responsible for ethene production in bacteria of the Pseudomonas syringae group.
  • In the other reaction (EC the enzyme catalyzes the mono- oxygenation of both 2-oxoglutarate and L-arginine, forming succinate, carbon dioxide and L-hydroxyarginine, which is subsequently cleaved into guanidine and (S)-1-pyrroline-5-carboxylate.
  • The enzymes catalyze two cycles of the ethene-forming reaction for each cycle of the succinate-forming reaction, so that the stoichiometry of the products ethene and succinate is 2:1.
