IntEnz Enzyme Nomenclature
EC 1.1.1.325

Names

Accepted name:
sepiapterin reductase (L-threo-7,8-dihydrobiopterin forming)
Systematic name:
L-threo-7,8-dihydrobiopterin:NADP+ oxidoreductase

Reactions

Comments:

This enzyme, isolated from the bacterium Chlorobium tepidum, catalyses the final step in the de novo synthesis of tetrahydrobiopterin from GTP. cf. EC 1.1.1.153, sepiapterin reductase (L-erythro-7,8-dihydrobiopterin forming).
