Protein
Nitrate reductase-like protein NarX: narX

Gene
narX
Protein
Nitrate/nitrite sensor protein NarX
Organism
Escherichia coli O157:H7
Length
598 amino acids
Function
Acts as a sensor for nitrate/nitrite and transduces signal of nitrate availability to the NarL protein and of both nitrate/nitrite to the NarP protein. NarX probably activates NarL and NarP by phosphorylation in the presence of nitrate. NarX also plays a negative role in controlling NarL activity, probably through dephosphorylation in the absence of nitrate (By similarity).
