| phenylalanine | <amino acid> One of the amino acids which the body cannot manufacture itself, but must acquire from food. It is abundant in meats and cheese. Phenylalanine is a precursor of tyrosine and together they lead to the formation of thyroxine or thyroid hormone and of adrenaline and noradrenaline which is converted into a neurotransmitter, a brain chemical which transmits nerve impulses. This neurotransmitter is used by the brain to manufacture noradrenaline which promotes mental alertness, memory, elevates mood and suppresses the appetite very effectively. Along with another amino acid, tryptophan, phenylalanine governs the release of an intestinal hormone called cholecystokinin. Overuse of phenylalanine supplements can cause anxiety, headaches and hypertension and are contraindicated for pregnant woman, those who suffer from anxiety attacks, high blood pressure, PKU, pigmented melanoma or anyone taking an anti-depressant containing monoamine oxidase inhibitors.

| phenylalanine 4-hydroxylase | <enzyme> An enzyme that catalyses the oxidation of l-phenylalanine to l-tyrosine with O2 and tetrahydrobiopterin (the latter forming the dihydro derivative) which is reduced by NADPH and a reductase to the active form; a deficiency of either of these enzymes will result in phenylketonuria. Synonym: phenylalanine 4-hydroxylase. (05 Mar 2000) |
| phenylalanine 4-monooxygenase | <enzyme> An enzyme that catalyses the oxidation of l-phenylalanine to l-tyrosine with O2 and tetrahydrobiopterin (the latter forming the dihydro derivative) which is reduced by NADPH and a reductase to the active form; a deficiency of either of these enzymes will result in phenylketonuria.

| phenylalanine ammonia lyase | <enzyme> An enzyme that catalyses the deamination of l-phenylalanine to form trans-cinnamate and ammonia. It may also act on l-tyrosine. Since the enzyme deprives neoplastic tissue of phenylalanine, it has been used experimentally in the treatment of acute lymphoblastic leukaemia. The enzyme is obtained from many plants and is used as an enzymic marker for lignification and other developmental processes in plant cells. Pharmacological action: antineoplastic agent. Chemical name: L-Phenylalanine ammonia-lyase Registry number: EC 4.3.1.5 (12 Dec 1998) |
| phenylalanine hydroxylase | <enzyme> An enzyme of the oxidoreductase class that catalyses the reaction l-phenylalanine, tetrahydrobiopterin, and oxygen to yield l-tyrosine, dihydrobiopterin, and water, the reaction synthesizing tyrosine from phenylalanine. Chemical name: L-Phenylalanine,tetrahydrobiopterin:oxygen oxidoreductase (4-hydroxylating) Registry number: EC 1.14.16.1 (12 Dec 1998) |

| phenylalanine-trna ligase | <enzyme> An enzyme that activates phenylalanine with its specific transfer RNA. Chemical name: Phenylalanine:tRNA(Phe) ligase (AMP-forming) Registry number: EC 6.1.1.20 (12 Dec 1998) |
| n-formylmethionine leucyl-phenylalanine | <chemical> N-formylmethionyl-leucyl-phenylalanine. A formylated tripeptide originally isolated from bacterial filtrates that is positively chemotactic to polymorphonuclear leucocytes, and causes them to release lysosomal enzymes and become metabolically activated. Chemical name: L-Phenylalanine, N-(N-(N-formyl-L-methionyl)-L-leucyl)- (12 Dec 1998) |

| 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 |
Used by the brain to produce dopamine and norepinephrine, chemicals that promote alertness, elevate mood, decrease pain, aid in memory and learning, and reduce hunger and appetite. Caution: Phenylalanine should not be supplemented by individuals with anxiety attacks, diabetes, pigmented melanoma (skin cancer), high blood pressure, or if pregnant.

| 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.
