摘要：
A study is conducted to discuss the mononuclear molybdenum enzymes. Enzymes containing molybdenum in their active sites have been recognized with more than 50 molybdenum-containing enzymes being purified and biochemically characterized. It is well-established that all molybdenum-containing enzymes other than nitrogenase fall into three large and mutually exclusive families, as exemplified by the enzymes xanthine oxidase, sulfite oxidase, and DMSO reductase. The structures of the three canonical molybdenum centers in their oxidized Mo(VI) states are examined along with that for the pyranopterin cofactor. The active sites of members of the xanthine oxidase family ALSO have an LMoVIOS-(OH) structure with a square-pyramidal coordination geometry.
