2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)

2-oxoglutarate + L-arginine + O₂ = succinate + CO₂ + guanidine + (S)-1-pyrroline-5-carboxylate + H₂O (overall reaction);;(1a) 2-oxoglutarate + L-arginine + O₂ = succinate + CO₂ + L-hydroxyarginine;;(1b) L-hydroxyarginine = guanidine + (S)-1-pyrroline-5-carboxylate + H₂O

L-arginine,2-oxoglutarate:oxygen oxidoreductase (succinate-forming)

This is one of two simultaneous reactions catalysed by the enzyme, which is responsible for ethylene production in bacteria of the Pseudomonas syringae group.In the other reaction [EC 1.13.12.19, 2-oxoglutarate dioxygenase (ethylene-forming)] the enzyme catalyses the dioxygenation of 2-oxoglutarate forming ethylene and three molecules of carbon dioxide.The enzyme catalyses two cycles of the ethylene-forming reaction for each cycle of the succinate-forming reaction, so that the stoichiometry of the products ethylene and succinate is 2:1.
