The enzyme, best characterized from the sulfate-reducing bacterium Megalodesulfovibrio gigas, belongs to the xanthine oxidase family of enzymes. However, it lacks the FAD-binding domain typically found in members of this family. Instead, it transfers electrons to flavodoxin, which fulfills the role of the missing domain. The enzyme contains a molybdenum-molybdopterin-cytosine dinucleotide (MCD) cofactor and two types of [2Fe-2S] clusters per monomer.
