Specific Function:
isomerase activity

Specific Function:
The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The gamma chain is a membrane-embedded heme-iron unit resembling cytochrome b, which transfers electrons from quinones to the beta subunit

Specific Function:
Chaperone required for proper molybdenum cofactor insertion and final assembly of the membrane-bound respiratory nitrate reductase 1. Required for the insertion of the molybdenum into the apo-NarG subunit, maybe by keeping NarG in an appropriate competent-open conformation for the molybdenum cofactor insertion to occur. NarJ maintains the apoNarGH complex in a soluble state. Upon insertion of the molybdenum cofactor, NarJ seems to dissociate from the activated soluble NarGH complex, before its association with the NarI subunit on the membrane

Specific Function:
The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The beta chain is an electron transfer unit containing four cysteine clusters involved in the formation of iron-sulfur centers. Electrons are transferred from the gamma chain to the molybdenum cofactor of the alpha subunit

Specific Function:
The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The alpha chain is the actual site of nitrate reduction

Specific Function:
Involved in excretion of nitrite produced by the dissimilatory reduction of nitrate

Specific Function:
Not Available

Specific 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

Specific Function:
sequence-specific DNA binding transcription factor activity, DNA binding
