일반 설명
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.
애플리케이션
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.
생화학적/생리학적 작용
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.

Prodrug activation gene therapy for cancer involves expressing prodrug-activating enzymes in tumour cells, so they can be selectively killed by systemically administered prodrug. For example, Escherichia colinfsB nitroreductase (E.C. 1.6.99.7)(NTR), sensitises cells to the prodrug CB1954 (5-[aziridin-1-yl]-2,4-dinitrobenzamide), which it converts

A fundamental obstacle in gene therapy for cancer treatment is the specific delivery of an anticancer gene product to a solid tumor. Although several strategies exist to control gene expression once a vector is directly introduced into a tumor, as
