Comments Catalyses 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.
Cofactor
History
Reactions 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].
