Modulation of Human Phenylalanine Hydroxylase by 3-Hydroxyquinolin-2(1H)-One Derivatives [PDF]
Biomolecules, 2021 Phenylketonuria (PKU) is a genetic disease caused by deficient activity of human phenylalanine hydroxylase (hPAH) that, when untreated, can lead to severe psychomotor impairment.

The Pah-R261Q mouse reveals oxidative stress associated with amyloid-like hepatic aggregation of mutant phenylalanine hydroxylase [PDF]
Nature Communications, 2021 Phenylketonuria (PKU) is caused by autosomal recessive variants in phenylalanine hydroxylase (PAH) and can lead to neurotoxicity. Here the authors describe a mouse model of PKU based on a mutation in phenylalanine hydroxylase (R261Q) which replicates ...

Phenylalanine hydroxylase mRNA rescues the phenylketonuria phenotype in mice [PDF]
Frontiers in Bioengineering and Biotechnology, 2022 Phenylketonuria (PKU) is an inborn error of metabolism caused by a deficiency in functional phenylalanine hydroxylase (PAH), resulting in accumulation of phenylalanine (Phe) in patients’ blood and organs.

Allosteric regulation of phenylalanine hydroxylase [PDF]
Archives of Biochemistry and Biophysics, 2012 The liver enzyme phenylalanine hydroxylase is responsible for conversion of excess phenylalanine in the diet to tyrosine. Phenylalanine hydroxylase is activated by phenylalanine; this activation is inhibited by the physiological reducing substrate tetrahydrobiopterin.

A unique dual activity amino acid hydroxylase in Toxoplasma gondii. [PDF]
PLoS ONE, 2009 The genome of the protozoan parasite Toxoplasma gondii was found to contain two genes encoding tyrosine hydroxylase; that produces L-DOPA. The encoded enzymes metabolize phenylalanine as well as tyrosine with substrate preference for tyrosine.

Identification of the Allosteric Site for Phenylalanine in Rat Phenylalanine Hydroxylase. [PDF]
J Biol Chem, 2016 Liver phenylalanine hydroxylase (PheH) is an allosteric enzyme that requires activation by phenylalanine for full activity. The location of the allosteric site for phenylalanine has not been established. NMR spectroscopy of the isolated regulatory domain (RDPheH(25-117) is the regulatory domain of PheH lacking residues 1-24) of the rat enzyme in the ...

Detection of IVS4+1G>A mutation in phenylalanine hydroxylase gene in North of Iran using PCR-sequencing [PDF]
Journal of Shahrekord University of Medical Sciences, 2023 Background and aims: Phenylketonuria (PKU) is an autosomal recessive disorder of phenylalanine (Phe) metabolism. Mutations in the phenylalanine hydroxylase (PAH) gene are the main reason for the incidence of PKU.

Mouse phenylalanine hydroxylase. Homology and divergence from human phenylalanine hydroxylase [PDF]
Biochemical Journal, 1990 The laboratory mouse represents an important model for the study of phenylalanine metabolism and the pathochemistry of phenylketonuria, yet mouse phenylalanine hydroxylase (PAH) has not been extensively studied. We report the cloning and sequencing of a mouse PAH cDNA, the expression of enzymic activity from the mouse PAH cDNA clone and the ...
