On Regulating the Synthesis of Nitrate Reductase
Denitrification plays an important role in the nitrogen budget of soil and water. It is carried out only by bacteria and provides a means for them to generate metabolic energy anaerobically, by utilizing various nitrogenous oxides as terminal electron acceptors in place of oxygen. Reduction of nitrate to nitrite, the first step in the denitrification pathway, is catalyzed by dissimilatory nitrate reductase (DNR). It is clear that study devoted to the structure and function of this enzyme, and to the regulation of its synthesis and activity, will help to form a clearer picture of the various factors controlling denitrification.
