WebMolybdenum cofactor biosynthesis. Molybdenum cofactor (MoCo) is needed by three enzymes in humans: sulfite oxidase, xanthine oxidase and aldehyde oxidase. The pathway of its synthesis is so conserved that plants and bacteria can readily use human enzymes. Bacteria, however, diverge after the first three steps from this path and their final MoCo ... WebMolybdenum cofactor deficiency is a rare metabolic disorder characterized by severe and rapidly progressive neurologic damage caused by the functional loss of sulfite oxidase, one of four molybdenum-dependent enzymes. Until recently, no effective therapy was available, and early fatality was the usual outcome.
