ENZYME entry: EC 2.8.1.12

PURL: https://purl.expasy.org/enzyme/EC/2.8.1.12
Accepted Name
molybdopterin synthase
Alternative Name(s)
MPT synthase
Reaction catalysed
2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal-Gly-aminoethanethioate + cyclic pyranopterin phosphate + H2O = molybdopterin + 2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly + 2 H(+)
Comment(s)
  • 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.
