ENZYME entry: 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-NH-CH2-C(O)SH + cyclic pyranopterin phosphate + H2O <=> 2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly + 4 H(+) + molybdopterin

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.
