Protein

Respiratory nitrate reductase 1 beta chain

Gene

narH

Organism
Shigella flexneri
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

The nitrate reductase enzyme complex allows S.flexneri 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 (By similarity).By similarity

Catalytic activityi

Nitrite + acceptor = nitrate + reduced acceptor.

Cofactori

Binds 3 4Fe-4S clusters per subunit.By similarity
Binds 1 3Fe-4S cluster per subunit.By similarity
