Nitrate reductase (NR) catalyzes the reduction of NO3 to NO2 using NADPH . NR active site contains Mo atom. Four types of NR are known: one eukaryotic assimilatory NR and 3 bacterial NRs – cytoplasmic assimilatory (NAC), membrane-bound respiratory (NAR) and periplasmic dissimilatory (NAP). The cofactors of NR are Molybdopterin (MPT) in eukaryotic NR and bis-Molybdopterin guanine dinucleotide (MGD) in bacterial NR.
