| phenylalanine hydroxylase |
Phenylalanine hydroxylase (eg. EC 1.14.16.1) is an enzyme which catalyses the reaction causing the addition of an hydroxyl group to the end of the 6-carbon aromatic ring of phenylalanine, such that it becomes tyrosine. Phenylalanine hydroxylase is the rate-limiting enzyme of the metabolic pathway which degrades excess phenylalanine. Mutations in phenylalanine hydroxylase which result in lower activity are the cause of the disease phenylketonuria, or PKU. ...

| phenylalanine 4-monooxygenase |
a monooxygenase that activates molecular oxygen to catalyze the oxidation of phenylalanine to tyrosine, activating oxygen via oxidation of the cofactor tetrahydrobiopterin to dihydrobiopterin. Deficiency of the enzyme results in hyperphenylalaninemia.
