Nitroreductase Protein, B. subtilis (His)

Nitroreductase is an enzyme that reduces nitro groups on substrates to amino groups. Nitroreductase plays a role in the bioactivation of prodrugs particularly in applications related to cancer therapeutic strategies. Nitroreductase Protein, B. subtilis (His) is the recombinant Nitroreductase protein, expressed by E. coli, with His tag^[1][2].

Nitroreductase is an enzyme that reduces nitro groups on substrates to amino groups and has a molecular mass of approximately 24 kDa. Nitroreductase is expressed mainly in bacterial species. Nitroreductase has functions in cellular processes involving redox reactions. Nitroreductase participates in the breakdown of nitroaromatic compounds which is critical for the detoxification of these potentially harmful substances. Nitroreductase is involved in the drug metabolism pathway specifically under the xenobiotic degradation category. Nitroreductase has the ability to transform prodrugs to active cytotoxic compounds, which makes it significant in research for targeted cancer treatments. Clinical strategies often focus on exploiting Nitroreductase to selectively activate therapeutics within cancer cells. Additionally, nitroreductase's activity influences the nitrogen cycle partnering with proteins like flavin reductase in biochemical reactions^[1][2].

Nitroreductase Protein, B. subtilis (His) has an affinity to CB1954 (HY-13543), but the reaction occurs slowly^[1].
Nitroreductase Protein, B. subtilis (His) is found to biotransform TNT to the product 2-amino 4,6-DNT^[1].
Nitroreductase Protein, B. subtilis (His) reduces both CB1954 and Menadione (HY-B0332) in the presence of NADH and NADPH^[2].
Nitroreductase Protein, B. subtilis (His) produces 4-hydroxylamine derivative of CB1954^[2].
