Biopterin refers to a number of pterin coenzymes produced and utilised by many species including humans and animals. Biopterins and similar compounds are also found in some bacteria and fungi. Biopterins act as cofactors for aromatic amino acid hydroxylases, which produce a number of neurotransmitters including dopamine, norepinepherine, epinepherine, and seratonin. They are also required for the production of nitric oxide, which is also used in cell-cell signalling, most notably in regulating blood pressure by dilating blood vessels.
