EC 1.14.20.7 Details
show Brenda entryEC number
1.14.20.7
Accepted name
2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)
Reaction
L-arginine + 2-oxoglutarate + O2 = succinate + CO2 + guanidine + (S)-1-pyrroline-5-carboxylate + H2O (overall reaction);;(1a) L-arginine + 2-oxoglutarate + O2 = succinate + CO2 + 5-hydroxy-L-arginine;;(1b) 5-hydroxy-L-arginine = guanidine + (S)-1-pyrroline-5-carboxylate + H2O
Other name(s)
ethene-forming enzyme,
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 (ethene-forming)] the enzyme catalyses the dioxygenation of 2-oxoglutarate forming ethene and three molecules of carbon dioxide.The enzyme catalyses 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.
