an aromatic amine + 3 NAD(P)+ + 2 H2O = an aromatic nitrate + 3 NAD(P)H + 3 H+
(overall reaction)
an aromatic amine + 3 NAD(P)+ + 2 H2O = an aromatic nitrate + 3 NAD(P)H + 3 H+
in vivo the reaction is obseverved in the opposite direction from that shown in the equation
an aromatic amine + NAD(P)+ + H2O = an aromatic hydroxylamine + NAD(P)H + H+
(1a)
an aromatic hydroxylamine + NAD(P)+ = an aromatic nitric oxide + NAD(P)H + H+
(1b)
an aromatic nitric oxide + NAD(P)+ + H2O = an aromatic nitrate + NAD(P)H + H+
(1c)
