show Brenda entryEC number
1.14.11.34
Accepted name
2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)
Reaction
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
Other name(s)
ethylene-forming enzyme,
EFE
Systematic name
L-arginine,2-oxoglutarate:oxygen oxidoreductase (succinate-forming)
Comment
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.
