Tetrahydrobiopterin (BH 4 ) deficiency accounts for 1-3% of all reported forms of hyperphenylalaninaemia (HPA). Deficiencies of two enzymes, GTP-cyclohydrolase (GTPch; EC 3.5.4.16) and 6-pyruvoyl tetrahydropterin synthase (6-PTS), lead to a defect in

Tetrahydrobiopterin (BH4) deficiency comprises a group of very rare diseases characterized by progressive neurological symptoms unresponsive to treatment with low-phenylalanine diet. 6-Pyruvoyl-tetrahydropterin synthase deficiency, the most common fo

The biosynthesis of tetrahydrobiopterin from either dihydroneopterin triphosphate, sepiapterin, dihydrosepiapterin or dihydrobiopterin was investigated using extracts from human liver, dihydrofolate reductase and purified sepiapterin reductase from h

Four adolescent or young adult patients with phenylketonuria were examined before and after discontinuation of dietary treatment. Plasma and CSF phenylalanine concentrations increased about two-fold in three patients. In these patients the CSF concen

The biosynthetic pathway of tetrahydrobiopterin (BH(4)) from dihydroneopterin triphosphate (NH(2)P(3)) was studied in fresh as well as heat-treated human liver extracts. The question of NAD(P)H dependency for the formation of sepiapterin was examined
