Structural insight into the dioxygenation of nitroarene compounds: the crystal structure of nitrobenzene dioxygenase.

Nitroaromatic compounds are used extensively in many industrial processes and have been released into the environment where they are considered environmental pollutants. Nitroaromatic compounds, in general, are resistant to oxidative attack due to the electron-withdrawing nature of the nitro groups and the stability of the benzene ring. However, the bacterium Comamonas sp.
