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.

Dynamic regulation of phenylalanine hydroxylase
Pteridines, 2014 Phenylalanine hydroxylase (PAH) is the key enzyme in phenylalanine metabolism, catalyzing its oxidative breakdown to tyrosine. Its function in the committed step of amino acid metabolism requires strict regulation. Thus, several regulatory mechanisms are

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 ...
