Metabolite Identification
Common NameMolybdopterin precursor Z
DescriptionMolybdopterin precursor Z is a molybdopterin precursor. All molybdenum-containing oxotransferases use molybdenum in the form of a pterin-containing cofactor. In some of these enzymes, this cofactor consists of molybdenum ligated to a phosphorylated pterin, called molybdopterin (MPT). MPT is a tricyclic pyranopterin containing a cis-dithiolene group. Together, the metal and the pterin moiety form the redox reactive molybdenum cofactor (MoCo). Conversion of precursor Z to molybdopterin requires the opening of a cyclic phosphate to produce a terminal mono-ester and the transfer of sulfur to generate the dithiolene function essential for molybdenum ligation. Molybdopterin (MPT)-synthase is the enzyme necessary for the conversion of precursor Z into molybdopterin. The large and small subunits of molybdopterin synthase are both encoded from a single gene by overlapping open reading frames. Mutations in patients with deficiencies in MoCo biosynthesis usually occur in the enzymes catalyzing the first and second steps of biosynthesis, leading to the formation of precursor Z and MPT, respectively. The second step is catalyzed by the heterotetrameric MPT synthase protein consisting of two large (MoaE) and two small (MoaD) subunits with the MoaD subunits located at opposite ends of a central MoaE dimer. Previous studies have determined that the conversion of the sulfur- and metal-free precursor Z to MPT by MPT synthase involves the transfer of sulfur atoms from a C-terminal MoaD thiocarboxylate to the C-1' and C-2' positions of precursor Z.
