Description
A flavoprotein (FAD). The enzyme displaces a diverse range of substituents from the 4-position of polyhalogenated phenols but requires that a halogen substituent be present at the 2-position. The enzyme converts many polyhalogenated phenols into hydroquinones, and requires that a halogen substituent be present at C-2. If C-4 carries a halogen substituent, reaction 1 is catalysed, e.g. 2,4,6-triiodophenol is oxidized to 2,6-diiodohydroquinone; if C-4 is unsubstituted, reaction 2 is catalysed
