Nitrate reductase

Nitrogen assimilation converts nitrate, nitrite, or ammonium into glutamine and glutamate, thereby supplying nitrogen for the synthesis of amino acids, nucleotides, and other nitrogen-containing compounds. Different key enzymes have clearly defined roles in substrate affinity, energy ...

Nitrate reduction is a key reaction in the biological nitrogen cycle that determines the fate of NO₃⁻. After NO₃⁻ is reduced to NO₂⁻, it can enter denitrification, DNRA, or assimilatory utilization pathways, which respectively affect nitrogen removal, nitrogen retention, and biomass ...
