Abstract: The peroxidase catalyzed aerobic oxidation of aromatic pyruvates produces the aromatic aldehyde, oxalate, CO and CO2 and a weak light emission. This indicates the preliminary formation of a peroxy anion which can cyclizes to a four-membered ring dioxetane and to a five membered ring α-keto-β-peroxylactone intermediates. The possible importance of this new source of carbon oxides in biological systems is pointed out. The results considerably strengthen the view that a dioxetane is formed in side chain of the plant hormone indoleacetic acid during the oxidation catalyzed by peroxidase. © 1980.
