6-pyruvoyltetrahydropterin synthase.
based on mapping to UniProt P27213
7,8-dihydroneopterin 3'-triphosphate = 6-pyruvoyl-5,6,7,8- tetrahydropterin + triphosphate.
-!- 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.
