Figure 1 shows reduction of nitrite synthetase activity of hydraoxalamine oxidoreductase (HAO) in presence of hydrogen peroxide (H2O2).

Mutagenesis of nrfA in C. jejuni resulted in the complete absence of NrfA protein in periplasmic extracts, as evidenced by immunoblotting with cross-reactive anti-E. coli NrfA antibodies (data not shown)

Figure 5. Shows the nrfA mutant when compared with the WT strain detoxifies NO under aerobic and anerobic conditions.

Hydroxylamine is oxidized to nitrite by hydroxylamine oxidoreductase (HAO) in the periplasm of Nitrosomonas europaea (p.3148)

Table 2 and Figure 4 demonstrated hydrazine conversion by the anammox culture

Table 1 indicates that the enzyme is reduced in the presence of sodium nitrite

Figure 5- Tetrathionate formation from thiosulfate and sulfate formation from thiosulfate; Figure 1- purified thiosulfate and reduce tetrathionate

Figure 3a Wild Type stain of C. jejuni with nrfA gene shows growth under limited oxygen with nitrite, while mutant strain (without nfrA) shows no growth

Protein film voltammetry (PFV) was used to analyze the catalytic activity of the E. coli nrfA gene in reducing NO. Figure 3 shows data for NO reduction for varying concentration of NO by nfrA. Table 1 compares nrfA activity between NO and other substrates.
