Abstract excerpt
Aminonitrotoluenes form rapidly from the reduction of dinitrotoluenes (DNTs) which are priority pollutants and animal carcinogens. For example, 4-amino-2-nitrotoluene (4A2NT) and 2A4NT accumulate from the reduction of 2,4-DNT during its aerobic biodegradation. Here, we show that 2,4-DNT dioxygenase (DDO) from Burkholderia sp. strain DNT oxidizes the aminonitrotoluenes 2A3NT, 2A6NT, 4A3NT, and 5A2NT to...
