| 1.9.6.1 | Mo5+ |
NapA contains a molybdo-bis(molybdopterin guanine dinucleotide) cofactor. The molybdenum ion coordination sphere of NapA includes two molybdopterin guanine dinucleotide dithiolenes, a protein-derived cysteinyl ligand and an oxygen atom. The Mo-O bond length is 2.6 A, which is indicative of a water ligand. In NapA or NapAB, the Mo5+ state can not be further reduced to Mo4+. A catalytic cycle for NapA is proposed in which nitrate binds to the Mo5+ ion and where a stable des-oxo Mo6+ species may participate |

| 1.9.6.1 | Molybdenum |
molybdenum-containing enzyme, the nitrate molecule binds to the active site with the molabdenum ion in the +6 oxidation state, electron transfer to the active site occurs only in the proton-electron transfer stage, where the molybdenum-V species plays an important role in catalysis |
