metabolism
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
physiological function
isoform NIA1 is the more efficient nitrite reductase while isoform NIA2 exhibits higher nitrate reductase activity
