Metabolite Identification
Common NameDyspropterin
DescriptionDyspropterin belongs to the class of organic compounds known as pterins and derivatives. These are polycyclic aromatic compounds containing a pterin moiety, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. Dyspropterin is a moderately basic compound (based on its pKa). Dyspropterin exists in all living organisms, ranging from bacteria to humans. Within humans, dyspropterin participates in a number of enzymatic reactions. In particular, dyspropterin and pppi can be biosynthesized from dihydroneopterin triphosphate; which is mediated by the enzyme 6-pyruvoyl tetrahydrobiopterin synthase. In addition, dyspropterin can be converted into 1-hydroxy-2-oxopropyl tetrahydropterin through its interaction with the enzyme sepiapterin reductase. In humans, dyspropterin is involved in the metabolic disorder called hyperphenylalaninemia due to guanosine triphosphate cyclohydrolase deficiency.
