General annotation (Comments)

Function

Simultaneously catalyzes two reactions, namely formation of ethylene and of succinate from 2-oxoglutarate, with a molar ratio of 2:1. Ref.3

Catalytic activity

2-oxoglutarate + O2 = ethylene + 3 CO2 + H2O.

2-oxoglutarate + L-arginine + O2 = succinate + CO2 + guanidine + (S)-1-pyrroline-5-carboxylate + H2O.

Cofactor

Fe2+.

Enzyme regulation

Activated by catalase. Inhibited by chelating reagents such as EDTA and Tiron (4,5-dihydroxy-1,3-benzene disulphonic acid), and by DTNB (5,5'-dithio-bis-2-nitrobenzoate) and hydrogen peroxide.

Pathway

Alkene biosynthesis; ethylene biosynthesis via 2-oxoglutarate.

Subunit structure

Monomer.

Miscellaneous

A dual-circuit mechanism has been proposed in Ref.3 for the complete reaction, in which the binding of L-arginine and 2-oxoglutarate in a Schiff-base structure generates a common intermediate for the two reactions.

Sequence similarities

Belongs to the iron/ascorbate-dependent oxidoreductase family.

Contains 1 Fe2OG dioxygenase domain.

Biophysicochemical properties

Kinetic parameters:

KM=59 µM for Fe2+

KM=19 µM for 2-oxoglutarate

KM=18 µM for L-arginine

pH dependence:

Optimum pH is 7.0-7.5.

Temperature dependence:

Optimum temperature is 20-25 degrees Celsius.
