Nitrate reductase ( quinone) ( EC 1.7.5.1, nitrate reductase A, nitrate reductase Z, quinol/nitrate oxidoreductase, quinol-nitrate oxidoreductase, quinol:nitrate oxidoreductase, NarA, NarZ, NarGHI) is an enzyme with systematic name nitrite:quinone oxidoreductase. [1] [2] [3] [4] [5] [6] [7] This enzyme catalyses the following chemical reaction

nitrate + a quinol nitrite + a quinone + H2O

This is a membrane-bound enzyme which supports [anaerobic respiration] on nitrate.
