== Function ==
[https://www.uniprot.org/uniprot/NFSB_ECOLI NFSB_ECOLI] Reduction of a variety of nitroaromatic compounds using NADH (and to lesser extent NADPH) as source of reducing equivalents; two electrons are transferred. Capable of reducing nitrofurazone, quinones and the anti-tumor agent CB1954 (5-(aziridin-1-yl)-2,4-dinitrobenzamide). The reduction of CB1954 results in the generation of cytotoxic species.<ref>PMID:15684426</ref>
