Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Involved in the biosynthesis of tetrahydrobiopterin, an essential cofactor of aromatic amino acid hydroxylases. Catalyzes the transformation of 7,8-dihydroneopterin triphosphate into 6-pyruvoyl tetrahydropterin (By similarity).By similarity

Catalytic activityi

7,8-dihydroneopterin 3'-triphosphate = 6-pyruvoyl-5,6,7,8-tetrahydropterin + triphosphate.

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity

Pathwayi: tetrahydrobiopterin biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes tetrahydrobiopterin from 7,8-dihydroneopterin triphosphate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Putative 6-pyruvoyl tetrahydrobiopterin synthase (ptps-1)
  2. no protein annotated in this organism
  3. no protein annotated in this organism
This subpathway is part of the pathway tetrahydrobiopterin biosynthesis, which is itself part of Cofactor biosynthesis.
