In enzymology a nitroquinoline-N-oxide reductase (EC 1.7.1.9) is an enzyme that catalyzes the chemical reaction4-(hydroxyamino)quinoline N-oxide + 2 NAD(P)+ + H2O 4-nitroquinoline N-oxide + 2 NAD(P)H + 2 H+The 4 substrates of this enzyme are 4-hydroxyaminoquinoline N-oxide NAD+ NADP+ and H2O whereas its 4 products are 4-nitroquinoline N-oxide NADH NADPH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on other nitrogenous compounds as donors with NAD+ or NADP+ as acceptor.
