Metabolite Identification
Common NameTetrahydrobiopterin
DescriptionL-erythro-tetrahydrobiopterin, also known as 5,6,7,8-tetrahydrobiopterin or 6R-BH4, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland. L-erythro-tetrahydrobiopterin is a drug which is used for the treatment of tetrahydrobiopterin (bh4) deficiency. L-erythro-tetrahydrobiopterin exists in all living organisms, ranging from bacteria to humans. In cattle, L-erythro-tetrahydrobiopterin is involved in the metabolic pathway called the phenylalanine and tyrosine metabolism pathway. Based on a literature review a significant number of articles have been published on L-erythro-tetrahydrobiopterin.

Enzymes

General function:
Inorganic ion transport and metabolism
Specific function:
Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.

Specific function:
Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In macrophages, NO mediates tumoricidal and bactericidal actions. Also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such PTGS2/COX2. As component of the iNOS-S100A8/9 transnitrosylase complex involved in the selective inflammatory stimulus-dependent S-nitrosylation of GAPDH implicated in regulation of the GAIT complex activity and probably multiple targets including ANXA5, EZR, MSN and VIM. Involved in inflammation, enhances the synthesis of proinflammatory mediators such as IL6 and IL8.
