3.D.4.10.4
Nitric oxide reductase of 787 aas and 14 TMSs, NorZ. This copper-A-dependent NOR uses cytochrome c₅₅₁
as electron donor but lacks menaquinol activity (Al-Attar and de Vries 2015). Employing reduced phenazine
ethosulfate (PESH) as electron donor, the main NO reduction pathway
catalyzed by Cu(A)Nor reconstituted in liposomes involves transmembrane
cycling of the PES radical. Cu(A)Nor reconstituted in
liposomes generates a proton electrochemical gradient across the
membrane similar in magnitude to cytochrome aa₃, suggesting that
bacilli using Cu(A)Nor to exploit NO reduction to increase cellular
ATP production (Al-Attar and de Vries 2015).
