The enzyme dehaloperoxidase (DHP) found in the marine worm Amphitrite ornata is capable of enzymatic peroxidation of 2,4-dichlorophenol (DCP) and 2,4-dibromophenol (DBP). There is also at least one parallel oxidative pathway and the major products 2-chloro-1,4-benzoquinone (2-ClQ) and 2-bromo-1,4-benzoquinone (2-BrQ) undergo aspontaneous secondary hydroxylation reaction. The oxidation and hydroxylation reactions have been monitored by UV-visible spectroscopy, High Performance Liquid Chromatography (HPLC), and mass spectrometry.
