Enzymatic Studies of Organohalogen Formation By Model Compounds
Blažková, Ivona ; Tesařová, E. ; Forczek, Sándor
Research in recent years has demonstrated that halogenated organic compounds are formed in\nnature due to biotic and abiotic processes. One of the most known sources of these substances are\nfrom the reaction catalyzed by haloperoxidases which include chloroperoxidase enzyme (CPO)\nisolated from Caldariomyces fumago. CPO enzyme was incubated with chloride or bromide, in the\npresence of hydrogen peroxide and organic substrates. Experiments were conducted with three\nsubstrates (acetone, acetic acid, and glucose), and different concentrations of halides.\nMeasurement of the samples by gas chromatography with an ECD detector showed the influence\nof the substrate type and halide concentration on the formation of the organohalogen products.
