nitroreductase family protein similar to the NAD(P)H nitroreductase MhqN
A diverse subfamily of the nitroreductase family containing uncharacterized proteins; includes nitroreductases MhqN, YodC, YdgI, DrgA. Nitroreductase catalyzes the reduction of nitroaromatic compounds such as nitrotoluenes, nitrofurans and nitroimidazoles. This process requires NAD(P)H as electron donor in an obligatory two-electron transfer and uses FMN as cofactor. The enzyme is typically a homodimer.
