== Disease ==
[https://www.uniprot.org/uniprot/PTPS_HUMAN PTPS_HUMAN] Defects in PTS are the cause of BH4-deficient hyperphenylalaninemia type A (HPABH4A) [MIM:[https://omim.org/entry/261640 261640]; also called 6-pyruvoyl-tetrahydropterin synthase deficiency (PTS deficiency) or hyperphenylalaninemia tetrahydrobiopterin-deficient due to PTS deficiency. HPABH4A is an autosomal recessive disorder characterized by depletion of the neurotransmitters dopamine and serotonin, and clinically by severe neurological symptoms unresponsive to the classic phenylalanine-low diet.<ref>PMID:10531334</ref> <ref>PMID:7698774</ref> <ref>PMID:8178819</ref> <ref>PMID:7493990</ref> <ref>PMID:8707300</ref> <ref>PMID:9222757</ref> <ref>PMID:9159737</ref> <ref>PMID:9450907</ref> <ref>PMID:10585341</ref> <ref>PMID:10220141</ref> <ref>PMID:10874306</ref> <ref>PMID:11388593</ref> 
== Function ==
[https://www.uniprot.org/uniprot/PTPS_HUMAN PTPS_HUMAN] 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.
