Comparative studies of nitrate-activated nitrate reductase (NR-NO2) and nitrate-induced nitrate reductase (NR-NO3) (EC indicate that the enzymes differ in structure, heat stability, and pH dependence, but have the same cofactor requirment. NR-NO2 developes in barley (Hordeum vulgare L. var. Dvir) seedlings as NR-NO3 disappears. A transition from the active to the inactive form of nitrate reductase takes place. Nitrite seems to activate the inactive form of the enzyme.
