Enzyme Information
| 1.1.1.153 |
Sepiapterin reductase (L-erythro-7,8-dihydrobiopterin forming).
based on mapping to UniProt Q64105
(1) L-erythro-7,8-dihydrobiopterin + NADP(+) = sepiapterin + NADPH. (2) L-erythro-tetrahydrobiopterin + 2 NADP(+) = 6-pyruvoyl-5,6,7,8- tetrahydropterin + 2 NADPH.
-!- 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.
