Abstract
Abstract Under aerobic conditions plant peroxidases can function as dihydroxyfumaric acid oxidases. Similarly, the enzyme is capable of reacting with molecular oxygen using the enolic form of various pentahydroxycyclohexanones as co-substrates. dl -3,5/4,6-Tetrahydroxycyclohexane-1,2-dione was demonstrated to be the product of this type of oxidation of 2,4,6/3,5-pentahydroxycyclohexanone. The system peroxidase-endiole-O 2 was also found to catalyze thehydroxylation of ri ng C-atoms of aromatic compounds. In an oxidase type of reaction this system is capable of dehydrogenating > CHNH bonds and producing ethylene from α-keto-γ-methylthiobutyric acid.
