| 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. Synonym: phenylalanine 4-hydroxylase. (05 Mar 2000) |

| phenylalanine aminopeptidase | <enzyme> Metalloenzyme from legionella pneumophila; mw: 35,000; pH optimum 8-9.5 Registry number: EC 3.4.11.- (26 Jun 1999) |
| 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 hydroxylase phosphatase | <enzyme> Catalyses dephosphorylation of phosphorylated phenylalanine hydroxylase Registry number: EC 3.1.3.- Synonym: phe hydroxylase phosphatase (26 Jun 1999) |
| phenylalanine oxidase | <enzyme> Forms phenylpyruvate in the presence of air; consider also phenylalanine dehydrogenase (nad) which requires nad Registry number: EC 1.4.3.- Synonym: phenylalanine desaminase, l-phenylalanine oxidase, phenylalanine dehydrogenase (26 Jun 1999) |
| 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) |
| phenylalanyl chain | A polypeptide component of insulin containing 30 amino acyl residues, beginning with a phenylalanyl residue (NH2-terminus); insulin is formed by the linkage of a B chain to an A chain by two disulfide bonds; the amino-acid composition of the B chain is a function of species. Synonym: phenylalanyl chain. (05 Mar 2000) |
| phenylalanyl-arginyl-aminopeptidase | <enzyme> An aspecific kininase Registry number: EC 3.4.11.- Synonym: phe-arg-aminopeptidase, phenylalanyl-arginylaminopeptidase (26 Jun 1999) |
| phenylamine | <chemistry> Any one of certain class of organic bases regarded as formed from ammonia by the substitution of phenyl for hydrogen. Origin: Phenyl + amine. Source: Websters Dictionary (01 Mar 1998) |
| phenylbenzene | <chemistry> A white crystalline substance, C6H5.C6H5, obtained by leading benzene through a heated iron tube. It consists of two benzene or phenyl radicals united. Origin: Pref. Di- + phenyl. Source: Websters Dictionary (01 Mar 1998) |
| phenylbutazone | <chemical> A drug that has anti-inflammatory, antipyretic, and analgesic activities. It is especially effective in the treatment of ankylosing spondylitis. It also is useful in rheumatoid arthritis and reiter's syndrome (investigational indication). Although phenylbutazone is effective in gouty arthritis, risk/benefit considerations indicate that this drug should not be employed for this disease. Pharmacological action: non-steroidal anti-inflammatory agents. Chemical name: 3,5-Pyrazolidinedione, 4-butyl-1,2-diphenyl- (12 Dec 1998) |
| phenylcarbinol | <chemical> A colourless liquid with a sharp burning taste and slight odour. It is used as a local anaesthetic and to reduce pain associated with lidocaine injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutic aid, and in perfumery and flavoring. Pharmacological action: anaesthetics, local, pharmaceutic aid. (12 Dec 1998) |
| phenyldichloroarsine | C6H5A5Cl2;A toxic liquid that has been used as a blister and vomiting agent by certain military and police organizations; it was first used in a limited manner in World War I. (05 Mar 2000) |
| phenylene | <chemistry> A hypothetic radical (C6H4) occurring in certain derivatives of benzene; as, phenylene diamine. Source: Websters Dictionary (01 Mar 1998) |

| phenylketonuria |
An inherited disorder resulting in the inability to process the amino acid, phenylananine. If not treated, the disorder may result in mental retardation. Treatment is a diet low in phenylalanine. Newborns are screened for PKU, in order to determine the need for treatment before brain damage occurs.
