Capable of dealkylating a model xenobiotic compound, 7-ethoxycoumarin. Metabolizes with high efficiency a wide range of xenobiotics, including alkoxycoumarins, alkoxyresorufins, and several herbicides of the class of phenylureas. Catalyzes the double N-dealkylation (oxidative N-demethylation) of phenylureas such as chlortoluron and isoproturon with turnover rates comparable to those reported for physiological substrates and produces non-phytotoxic compounds. Could be used for control of herbicide tolerance and selectivity, as well as soil and groundwater bioremediation. By aminopyrine and other xenobiotics. Belongs to the cytochrome P450 family.
