Figure 2: Dehalogenations of polychlorinated nitroaromatic compounds by monooxygenases. (a) Dehalogenation of pentachlorophenol by pentachlorophenol 4-monooxygenase; (b) dehalogenation of 2,4,5-trichlorophenol by chlorophenol 4-monooxygenase; (c) dehalogenation of 2, 4, 6-trichlorophenol by 2, 4, 6-trichlorophenol monooxygenase (d) sequential dehalogenation of 2, 4, 6-trichlorophenol by 2, 4, 6-trichlorophenol monooxygenase
