Metabolite Identification
Common Name4a-Hydroxytetrahydrobiopterin
DescriptionTetrahydrobiopterin (BH4) is essential for catalyzing the conversion of phenylalanine into tyrosine by phenylalanine hydroxylase. During this physiological reaction, the oxidation of BH4 creates 4a-hydroxytetrahydropterin (CAS: 70110-58-6) intermediates and hydrogen peroxide is formed. The hydrogen peroxide and the hydroxytetrahydropterin can both be derived from alternate breakdown routes of a common precursor, the corresponding 4a-hydroperoxytetrahydropterin (PMID: 8323303 ).

General function:
Involved in 4-alpha-hydroxytetrahydrobiopterin dehydratase activity
Specific function:
Involved in tetrahydrobiopterin biosynthesis. Seems to both prevent the formation of 7-pterins and accelerate the formation of quinonoid-BH2. Coactivator for HNF1A-dependent transcription. Regulates the dimerization of homeodomain protein HNF1A and enhances its transcriptional activity.
