摘要

Nfr-A1, a Bacillus subtilis nitroreductase, catalyzes the nitroreduction of a large panel of aromatic and heterocyclic nitro compounds, except those belonging to nitrouracil class of molecules. Besides nitroreduction, Nfr-A1 exhibits a strong NADH oxidase activity in the presence of oxygen, leading to high concentration of H2O2 (up to 200μM). In the presence of (N, N)-dimethyl-5-nitrouracil 1 (dim-NU), Nfr-A1 achieves the reduction of dim-NU ...
