Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 17 kDa (predicted molecular weight: 16 kDa).
IP 1/10 - 1/100.
IHC-P 1/250 - 1/500. Heat up to 98 °C, below boiling, and then let cool for 10-20 minutes.
ICC/IF 1/250 - 1/500.
  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function
      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.
    • Pathway
      Cofactor biosynthesis; tetrahydrobiopterin biosynthesis; tetrahydrobiopterin from 7,8-dihydroneopterin triphosphate: step 1/3.
    • Involvement in disease
      Defects in PTS are the cause of BH4-deficient hyperphenylalaninemia type A (HPABH4A) [MIM: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.
    • Sequence similarities
      Belongs to the PTPS family.
    • Post-translational
      Phosphorylation of Ser-19 is required for maximal enzyme activity.
