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. |
