MetaCyc Enzyme: 1-aminocyclopropane-1-carboxylate oxidase

Gene: ACO Accession Number: G-11917 (MetaCyc)

Species: Cucumis melo

Summary:
A cDNA clone was isolated from wounded fruit pericarp and leaf tissues of climateric and pre climateric Cucumis melo. The cDNA was recombinantly expressed in E.coli, purified and characterized. The encoded enzyme catalyzed the formation of ethylene [Balague93]. The protein showed 73-81% identity with tomato EFE (ethylene forming enzyme).

Molecular Weight of Polypeptide: 36.1 kD (from nucleotide sequence), 35.5 kD (experimental) [Balague93 ]

Enzymatic reaction of: 1-aminocyclopropane-1-carboxylate oxidase

EC Number: 1.14.17.4

L-ascorbate + 1-aminocyclopropane-1-carboxylate + H+ + oxygen <=> ethylene + L-dehydro-ascorbate + hydrogen cyanide + CO2 + 2 H2O

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

The reaction is physiologically favored in the direction shown.
