Allgemeine Beschreibung
Nitroreductase is a flavoprotein and is encoded by the NfsB gene. It comprises a dimer, with 217 amino acids and active site in each subunit. The structure has FMN and the substrate bound to the enzyme.
Anwendung
Nitroreductase from Escherichia coli has been used in the conjugation generation with pig liver esterase (PLE). It has also been used in chemiluminescence response studies with probes HyCL-3 and HyCL-4-AM in rat liver microsomes.
Biochem./physiol. Wirkung
Nitroreductase (NTR) catalyzes the reduction of nitroaromatic substrates and quinones. The mutant F124K of NTR is useful in cancer therapy and improves sensitization of drug CB1954.
Nitroreductase increases the sensitivity of organisms to nitro-containing drugs such as metronidazole by converting the nitro group to a cytotoxic nitro radical.
Nitroreductases can play a crucial role in redox systems via NADPH or NADH as a reductant.
Shows ability to reduce quinines. Enzyme for activating prodrugs in antibody directed enzyme prodrug therapy.
