Molybdenum and Biological Systems (Molybdenum Cofactors Containing Enzymes and Pathways)

Molybdenum and tungsten share several atomic properties. Hence, in order to distinguish them, microorganisms have evolved discriminating systems either at the level of metal insertion into the cofactor or during the possible interplay of molybdo-enzyme specific chaperones when incorporating the cofactor. Several different Mo transport systems have been identified in Prokaryotes and Eucaryotes with their relatively different regulation and storage systems.
