Metabolite Identification
Common NamePterin
DescriptionPterin, also known as 4-oxopterin or pteridoxamine, 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. Pterin exists in all living organisms, ranging from bacteria to humans. In cattle, pterin is involved in the metabolic pathway called the caffeine metabolism pathway. Based on a literature review a significant number of articles have been published on Pterin.

Enzymes

General function:
Amino acid transport and metabolism
Specific function:
Catalyzes the transfer of a methyl group from methyl-cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity).
