Cells acquire molybdenum and tungsten as their highly soluble oxoanions, Mo VI O 4 2− or W VI O 4 2−, which they internalize by means of an active (i.e. energy requiring) transmembrane importer, for subsequent conversion into the metalloenzyme cofactors Moco or Wco (and FeMoco in nitrogen fixers).This import system has been …
