   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 ...

   Nitric oxide synthase (NOS) is a key enzyme system that catalyzes the conversion of L-arginine into nitric oxide (NO) and L-citrulline. It participates in vascular homeostasis, neural signaling, immune inflammation, and redox regulation. NOS research should not focus only on changes in NO ...
