ENZYME entry: EC 4.2.3.12

Accepted Name
6-pyruvoyltetrahydropterin synthase
Alternative Name(s)
6-pyruvoyl tetrahydrobiopterin synthase
PTPS
Reaction catalysed
7,8-dihydroneopterin 3'-triphosphate <=> 6-pyruvoyl-5,6,7,8-tetrahydropterin + H(+) + triphosphate
Comment(s)
  • Catalyzes triphosphate elimination and an intramolecular redox reaction.
  • The product is 6-pyruvoyltetrahydrobiopterin.
  • Involved in the de novo synthesis of tetrahydrobiopterin from GTP, with the other enzymes involved being EC 1.1.1.153 and EC 3.5.4.16.
  • Formerly EC 4.6.1.10.
