Localization

Localization Comment Organism GeneOntology No. Textmining
membrane alpha and beta polypeptides, and therefore the active site for nitrate reduction, are located on the cytoplasmic side of the membrane. The gamma polypeptide is the only subunit which is embedded in the membrane Paracoccus denitrificans 16020

Subunits

Subunits Comment Organism
? alpha and beta polypeptides are essentially peripheral polypeptides that are attached to the membrane by protein-protein interactions, presumably via the gamma polypeptide Paracoccus denitrificans

Cofactor

Cofactor Comment Organism Structure
cytochrome b the enzyme contains two b-type hemes in the gamma subunit. The two b-type centres are functional parts of the enzyme Paracoccus denitrificans
