OverviewOverview

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. strain JS765 can grow with nitrobenzene as a sole, source of carbon, nitrogen and energy. Biodegradation is initiated by the, nitrobenzene dioxygenase (NBDO) system. We have determined the structure, of NBDO, which has a hetero-hexameric structure similar to that of several, other Rieske non-heme iron dioxygenases. The catalytic subunit contains a, Rieske iron-sulfur center and an active-site mononuclear iron atom. ... [(full description)]
