 2-211 5.40e-65

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.

 4-216 5.01e-06

nitroreductase similar to Escherichia coli NfsA; This family contains NADPH-dependent flavin reductase and oxygen-insensitive nitroreductase. These enzymes are homodimeric flavoproteins that contain one FMN per monomer as a cofactor. Flavin reductase catalyzes the reduction of flavin by using NADPH as an electron donor. Oxygen-insensitive nitroreductase, such as NfsA protein in Escherichia coli, catalyzes reduction of nitrocompounds using NADPH as electron donor.

nitroreductase family protein; A subfamily of the nitroreductase family containing uncharacterized proteins. 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.often found to be homodimers.

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.

oxidase similar to the microcin B17 processing protein McbC; This family is the oxidase domain of NRPS (non-ribosomal peptide synthetase) and other systems that modify polypeptides by cyclizing a thioester to form a ring. These include EpoB, part of the epothilone biosynthesis pathway; TubD, part of the tubulysin biosynthesis pathway, MtsD, part of the myxothiozol biosynthesis pathway; IndC, part of the indigoidine biosynthesis pathway and TfxB, part of the trifitoxin processing pathway. All are FMN-dependent and oxidize the product of the cyclization of thioesters in short polypeptides.
