Structural insights into urocanate reductase using room‐temperature X‐ray crystallography
The active‐site dynamics of the microbial enzyme urocanate reductase were revealed by room‐temperature X‐ray crystallography.Urocanate reductase (UrdA) is a bacterial enzyme that converts urocanic acid to imidazole propionate. Its catalytic residue Arg411 undergoes a large conformational change in the substrate‐bound versus product‐bound states.

A Host–Guest Platform for Highly Efficient, Quantitative, and Rapid Detection of Nitroreductase
Nitroreductase (NTR) is an enzyme expressed at an abnormally high level in solid tumors, which is associated with the hypoxia level in tumors. The establishment of a high-performance and convenient fluorescent platform for the fast monitoring of NTR is ...

Activation of 1-nitropyrene by nitroreductase increases the DNA adduct level and mutagenicity [PDF]
1-Nitropyrene (1-NP) is a mutagenic nitro compound in the environment. We studied correlations between the mutagenicity of 1-NP for three strains of Salmonella typhimurium, the activity of bacterial nitroreductases and the amount of 1-NP-derived DNA ...

Oncolytic adenovirus vectors for nitroreductase suicide gene therapy of prostate cancer [PDF]
Prostate cancer is the most common male cancer in the UK and USA, with a 1/13 chance of diagnosis and a 1/30 lifetime risk of death from the disease. Current treatment options include radiotherapy, surgery and hormone therapy, however 1/3 patients escape

Nitroreductase reactions of Arabidopsis thaliana thioredoxin reductase
Arabidopsis thaliana NADPH:thioredoxin reductase (TR, EC 1.6.4.5) catalyzed redox cycling of aromatic nitrocompounds, including the explosives 2,4,6-trinitrotoluene and tetryl, and the herbicide 3,5-dinitro-o-cresol. The yield of nitro anion radicals was equal to 70-90%.
