Chang, L.; Wie, L.I.; Audia, J.P.; Morton, R.A.; Schellhorn, H.E.
Expression of the Escherichia coli NRZ nitrate reductase is highly growth phase dependent and is controlled by RpoS, the alternative vegetative sigma factor (1999), Mol. Microbiol., 34, 756-766.

1.7.5.1	additional information	Escherichia coli	NRZ is expressed at a low level that is not influenced by anaerobiosis or nitrate. The NRZ operon is controlled mainly at the level of transcription and is induced 10fold at the onset of stationary phase in rich media. Expression of NRZ nitrate reductase is highly growth phase dependent and is controlled by the alternative vegetative sigma factor RpoS. RpoS-mediated regulation of NRZ may be an important physiological adaptation that allows the cell to use nitrate under stress-associated conditions	?	-	?
