FunFam 12: Molybdopterin synthase catalytic subunit

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Molybdopterin synthase. [EC: 2.8.1.12]
Cyclic pyranopterin phosphate + 2 [molybdopterin-synthase sulfur-carrier protein]-Gly-NH-CH(2)-C(O)SH + H(2)O = molybdopterin + 2 [molybdopterin- synthase sulfur-carrier protein].
  • Catalyzes the synthesis of molybdopterin from cyclic pyranopterin phosphate.
  • Two sulfur atoms are transferred to cyclic pyranopterin phosphate in order to form the characteristic ene-dithiol group found in the molybdenum cofactor.
  • Molybdopterin synthase consists of two large subunits forming a central dimer and two small subunits (molybdopterin-synthase sulfur- carrier proteins) that are thiocarboxylated at the C-terminus by EC 2.8.1.11, molybdopterin synthase sulfurtransferase.
  • The reaction occurs in prokaryotes and eukaryotes.
