This is the N-terminal tail of the respiratory nitrate reductase alpha chain. The nitrate reductase complex is a dimer of heterotrimers each consisting of an alpha, beta and gamma chain. The N-terminal tail of the alpha chain interacts with the beta chain and contributes to the stability of the heterotrimer [1].	Domain
