Nitroreductases (NRs) and ene-reductases (ERs) both utilize flavin mononucleotide cofactors but catalyze distinct reactions. NRs reduce nitroaromatics, whereas ERs reduce unsaturated C=C double bonds, and these functionalities are known to somewhat overlap. Recent studies on the ER xenobiotic reductase A
