Protein

Respiratory nitrate reductase 2 gamma chain

Gene

narV

Organism
Escherichia coli O157:H7
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

This is a second nitrate reductase enzyme which can substitute for the NRA enzyme and 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 (By similarity).By similarity

Catalytic activityi

Nitrite + acceptor = nitrate + reduced acceptor.

Cofactori

hemeBy similarityNote: Binds 2 heme groups per subunit. Heme 1 is located at the cytoplasmic interface, heme 2 is located at the periplasmic interface. Electrons are transferred from the periplasmic to the cytoplasmic heme.By similarity
