metabolism

Escherichia coli

the enzyme is necessary for nitrate/nitrite assimilation but also either detoxify nitrite or carries out fermentative ammonification in support of anaerobic catabolism. The enzyme confers a significant benefit during fermentative growth that reflects fermentative ammonification rather than detoxification. Fermentative ammonification by the enzyme allows for the energetically favorable fermentation of glucose to formate and acetate
