ENZYME entry: EC 2.7.7.80

Accepted Name
molybdopterin-synthase adenylyltransferase.
Reaction catalysed
[molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly + ATP + H(+) <=> [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly-AMP + diphosphate
Comment(s)
  • Adenylates the C-terminus of the small subunit of the molybdopterin synthase.
  • This activation is required to form the thiocarboxylated C-terminus of the active molybdopterin synthase small subunit.
  • The reaction occurs in prokaryotes and eukaryotes.
  • In the human, the reaction is catalyzed by the N-terminal domain of the protein MOCS3, which also includes a molybdopterin-synthase sulfurtransferase (EC 2.8.1.11) C-terminal domain.
  • Formerly EC 2.7.7.n4.
