Common NameL-erythro-tetrahydrobiopterin
DescriptionL-erythro-tetrahydrobiopterin is a pteridine derivative, classified as a biogenic cofactor involved in various enzymatic reactions, particularly in the synthesis of neurotransmitters. Its chemical structure features a bicyclic pteridine ring system with four hydrogenated carbon atoms, contributing to its role as a cofactor in the catalytic activity of aromatic amino acid hydroxylases, such as tyrosine hydroxylase (TH), which converts tyrosine to L-DOPA. Pathways involving L-erythro-tetrahydrobiopterin include its biosynthesis from GTP, as well as its production in organisms like Dictyostelium discoideum, where it is synthesized alongside its stereoisomer D-threo-tetrahydrobiopterin through the action of sepiapterin reductase (SR) (PMID:11778454 , PMID:21871890 ). In experimental settings, supplementation with L-erythro-tetrahydrobiopterin has been shown to stimulate residual TH activity, leading to enhanced L-DOPA production in cultured cells (PMID:22483312 , PMID:8889219 ). Additionally, studies have characterized the dopamine-releasing action of L-erythro-tetrahydrobiopterin, highlighting its significance in neurotransmitter regulation (PMID:7616241 ). Overall, L-erythro-tetrahydrobiopterin plays a crucial role in various biochemical pathways, particularly in the context of neurotransmitter synthesis and regulation.
