[Nitrate and nitrite reductase activity of milk xanthine oxidase].
The nitrate and nitrite reductase activities of milk xanthine oxidases were studied. The optimal conditions for manifestation of these activities were found. A possible mechanism of electron transport to nitrate and nitrite inside the enzyme is discussed.
