Molybdenum Oxotransferase and Oxo-transfer Reaction Lou Fuyan, Lu Xiaoming*, Song Fugen (Department of Chemistry, Capital Normal University Beijing 100037) Abstract Oxo-transfer reaction is catalyzed by molybdenum oxotransferase. This paper introduces the types and the classification of molybdenum oxotransferase, pterin cofactor of the oxomolybdoenzyme and oxo-transfer reaction. The current research state about oxotransferase catalysis mechanism and the transition state during the oxo-transfer reaction have been reviewed.
