8-210 3.48e-83

nitroreductase family protein; Proteins of this family catalyze the reduction of flavin or nitrocompounds using NAD(P)H as electron donor in a obligatory two-electron transfer, utilizing FMN or FAD as cofactor. They are often found to be homodimers. Enzymes of this family are described as NAD(P)H:FMN oxidoreductases, oxygen-insensitive nitroreductase, flavin reductase P, dihydropteridine reductase, NADH oxidase or NADH dehydrogenase.

nitroreductase family protein similar to Escherichia coli YdjA; A subfamily of the nitroreductase family containing uncharacterized proteins that are similar to nitroreductase YdjA from Escherichia coli. 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. Members of this family are also called NADH dehydrogenase, oxygen-insensitive NAD(P)H nitrogenase or dihydropteridine reductase.

nitroreductase similar to Escherichia coli NfsB; NAD(P)H:FMN oxidoreductase family. This domain catalyzes the reduction of flavin, nitrocompound, quinones and azo compounds using NADH or NADPH as an electron donor. The enzyme is a homodimer, and each monomer binds a FMN as co-factor. This family includes FRase I in Vibrio fischeri, wihich reduces FMN into FMNH2 as part of the bioluminescent reaction. The family also includes oxygen-insensitive nitroreductases that use NADH or NADPH as an electron donor in the ping pong bi bi mechanism. This type of nitroreductase can be used in cancer chemotherapy to activate a range of prodrugs.
