Tungsten: biological information

Biological role of tungsten: tungsten has a limited biological role. A number of enzymes (oxidoreductases) employ tungsten in a way related to molybdenum, (using tungsten.pterin complex). The structure of a tungstoenzyme aldehyde ferredoxin oxidoreductase is known (Protein Data Bank code 1AOR).
