spinqualitylabelsall models Bacterial periplasmic dissimilatory nitrate reductase containing Fe4S4 cluster with Mo, NO3 and molybdepterin guanine nucleotide (PDB entry 2jiq) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Nitrate reductase (NR) catalyzes the reduction of NO3 to NO2 using NADPH[1]. NR active site contains Mo atom. Four types of NR are known: eukaryotic assimilatory NR bacterial cytoplasmic assimilatory (NAC) bacterial membrane-bound respiratory (NAR) bacterial periplasmic dissimilatory (NAP). The cofactors of NR are Molybdopterin (MPT) in eukaryotic NR and bis-Molybdopterin guanine dinucleotide (MGD) in bacterial NR. Structural highlights . NAP active site includes a . The [2].
