The NO2 group is reduced to hydroxylamine[1]. NR uses FMN as cofactor. Among NRs are the oxygen-insensitive NAD(P)H NR and NADH dehydrogenase. Relevance NR is of special interest due to its potential use as activator of prodrugs in cancer therapy[2]. Structural highlights NR while the . Water molecules shown as red spheres.
