ENZYME entry: EC 1.1.1.153

Accepted Name
Sepiapterin reductase (L-erythro-7,8-dihydrobiopterin forming).
Reaction catalysed
  • L-erythro-7,8-dihydrobiopterin + NADP(+) <=> sepiapterin + NADPH
  • L-erythro-tetrahydrobiopterin + 2 NADP(+) <=> 6-pyruvoyl-5,6,7,8-tetrahydropterin + 2 NADPH
Comment(s)
  • This enzyme catalyzes the final step in the de novo synthesis of tetrahydrobiopterin from GTP.
  • The enzyme, which is found in higher animals and some fungi and bacteria, produces the erythro form of tetrahydrobiopterin.
  • Cf. EC 1.1.1.325.
