Enzyme Information

2.8.1.12

Molybdopterin synthase.

based on mapping to UniProt P30749

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.
