1.9.6.1	down	disruption of nasT leads to a marked decrease in nosZ and nap transcription in cells incubated in the presence of nitrate	-, 742380	
1.9.6.1	down	NarL represses the expression of periplasmic nitrate reductase NapAB under anaerobiosis	711653	
1.9.6.1	up	in the absence of nitrate, mutated nasS, which encodes the nitrate (NO3-)-sensor of the two-component NasST regulatory system, induces expression of nosZ and periplasmic nitrate reductase nap via nasT. Nitrate addition dissociates the NasS-NasT complex in vitro, suggesting the release of the activator NasT	-, 742380
