2-oxoglutarate dioxygenase (ethylene-forming)

2-oxoglutarate dioxygenase (ethylene-forming) (EC 1.13.12.19, ethylene-forming enzyme, EFE) is an enzyme with systematic name 2-oxoglutarate:oxygen oxidoreductase (decarboxylating, ethylene-forming).^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

2-oxoglutarate + O₂

\rightleftharpoons

ethylene + 3 CO₂ + H₂O

2-oxoglutarate dioxygenase produces ethylene in bacteria of the Pseudomonas syringae group.
