Description générale

Tetrahydrobiopterin is a natural cofactor for phenylalanine hydroxylase, tyrosine hydroxylase, tryptophan hydroxylase, nitric oxide synthase and alkylglycerol monooxygenase.

Application

(6R)-BH4 has been used as a buffer component for assaying tyrosine hydroxylase enzyme activity in mouse brain tissues. (6R)-BH4 has also been identified as an activator compound from a LOPAC library screen using a fluorogenic α-glucosidase assay.

Actions biochimiques/physiologiques

Lack of tetrahydrobiopterin may cause hyperphenylalaninemia. Diseases like, Parkinson′s, autism, depression and Alzheimer′s shows low concentration of tetrahydrobiopterin in the cerebrospinal fluid. This coenzyme participates in dopamine (DA) synthesis.

Biosynthesis of tetrahydrobiopterin starts from guanosine triphosphate by the action of guanosine triphosphate cyclohydrolase I, which yields the first intermediate, 7,8-dihydroneopterin triphosphate.
