Abstract The molybdenum cofactor (Moco) forms the active site of all eukaryotic molybdenum (Mo) enzymes. Moco consists of molybdenum covalently bound to two sulfur atoms of a unique tricyclic pterin moiety referred to as molybdopterin Molybdenum cofactor deficiency (MoCD) type A is a rare but devastating metabolic disease. It first appears in the newborn period. It is estimated to affect 1 in 200,000 newborns worldwide. MoCD typically appears in the first few weeks of life as In all organisms, Mo has to be complexed by a pterin compound, thereby forming the molybdenum cofactor (Moco), in order to gain biological activity.

molybdenum cofactor: ( mō-lib'dĕ-nŭm ), a complex of molybdenum and molybdopterin required for a number of enzymes. A deficiency of this cofactor will result in lower activities of sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase causing elevated levels of sulfite, thiosulfite, xanthine, etc The instability of the cofactor has been investigated and shown to be due to the oxygen sensitivity of the pterin ring and the reactivity of the sulfhydryl groups on the side chain. This work indicated the possibility that alkylation with iodoacetamide could lead to the production of a stable.
