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).
