2-oxoglutarate dioxygenase (ethene-forming)

2-oxoglutarate + O₂ = ethene + 3 CO₂ + H₂O

ethylene-forming enzyme, EFE, 2-oxoglutarate dioxygenase (ethylene-forming), 2-oxoglutarate:oxygen oxidoreductase (decarboxylating, ethylene-forming)

2-oxoglutarate:oxygen oxidoreductase (decarboxylating, ethene-forming)

This is one of two simultaneous reactions catalysed by the enzyme, which is responsible for ethene production in bacteria of the Pseudomonas syringae group. In the other reaction [EC 1.14.20.7, 2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)] the enzyme catalyses 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 catalyse 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.
