CC   -!- FUNCTION: Simultaneously catalyzes two reactions, namely formation of
CC       ethylene and of succinate from 2-oxoglutarate. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + 2 H(+) + O2 = 3 CO2 + ethene + H2O;
CC         Xref=Rhea:RHEA:31523, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC         ChEBI:CHEBI:18153; EC=1.13.12.19;
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + L-arginine + O2 = (S)-1-pyrroline-5-
CC         carboxylate + CO2 + guanidine + H(+) + H2O + succinate;
CC         Xref=Rhea:RHEA:31535, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:16526, ChEBI:CHEBI:16810,

CC         ChEBI:CHEBI:32682; EC=1.14.20.7;
CC   -!- COFACTOR:
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000250};
CC   -!- PATHWAY: Alkene biosynthesis; ethylene biosynthesis via 2-oxoglutarate.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- MISCELLANEOUS: A dual-circuit mechanism has been proposed in P.syringae
CC       pv phaseolicola for the complete reaction, in which the binding of L-
CC       arginine and 2-oxoglutarate in a Schiff-base structure generates a
CC       common intermediate for the two reactions.
CC   -!- MISCELLANEOUS: Encoded on an unnamed plasmid.
CC       {ECO:0000305|PubMed:18944747}.
CC   -!- SIMILARITY: Belongs to the iron/ascorbate-dependent oxidoreductase
CC       family. {ECO:0000305}.
