The role of molybdenum in human biology

1983-3-1  Molybdenum, because of its unique chemistry, is the biological catalyst for reactions in which proton and electron transfer, and possibly oxygen transfer, are coupled. The molybdoenzymes in man are sulphite oxidase, xanthine oxidase/dehydrogenase and aldehyde oxidase. The former is essential for detoxication of the sulphite arising from metabolism of sulphur-containing amino acids, from ...

The Molybdenum Cofactor* - Journal of Biological

The transition element molybdenum needs to be complexed by a special cofactor to gain catalytic activity. Molybdenum is bound to a unique pterin, thus forming the molybdenum cofactor (Moco), which, in different variants, is the active compound at the catalytic site of all molybdenum-containing enzymes in nature, except bacterial molybdenum nitrogenase.
