Mapping the Severity of Phenylalanine Hydroxylase Deficiency. [PDF]

open access: yesJ Inherit Metab Dis
ABSTRACT Since the 1960s, phenylalanine hydroxylase (PAH) deficiency can be detected via newborn screening, allowing early start of treatment to prevent severe intellectual disability. Precise determination of PAH deficiency severity continues to be hampered by several factors.

Mouse phenylalanine hydroxylase. Homology and divergence from human phenylalanine hydroxylase [PDF]

open access: yesBiochemical 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 ...

Effect of experimental phenylketonuria on some organs of pregnant mothers of albino rats and their young’s during perinatal life. [PDF]

open access: yesJournal of Bioscience and Applied Research, 2016
Phenylketonuria (PKU) is a genetic disorder that is characterized by an inability of the body to utilize the essential amino acid, phenylalanine.It results from a deficiency in phenylalanine hydroxylase, the enzyme catalyzing the conversion of ...

Sustained Correction of a Murine Model of Phenylketonuria following a Single Intravenous Administration of AAVHSC15-PAH

open access: yesMolecular Therapy: Methods & Clinical Development, 2020
Phenylketonuria is an inborn error of metabolism caused by loss of function of the liver-expressed enzyme phenylalanine hydroxylase and is characterized by elevated systemic phenylalanine levels that are neurotoxic.

PAH mutation spectrum and correlation with PKU manifestation in north Jiangsu province population

open access: yesKaohsiung Journal of Medical Sciences, 2018
Phenylketonuria (PKU) is a common autosomal recessive disorder of phenylalanine metabolism and mainly results a deficiency of phenylalanine hydroxylase gene (PAH). The incidence of various PAH mutations have race and ethnicity differences.

Phenylketonuria (PKU): A problem solved?

open access: yesMolecular Genetics and Metabolism Reports, 2016
Phenylketonuria (PKU) is a rare metabolic disorder characterized by impaired conversion of phenylalanine (Phe) to tyrosine. If left untreated, the resultant accumulation of excess blood Phe can cause physiological, neurological, and intellectual ...

BmPAH catalyzes the initial melanin biosynthetic step in Bombyx mori. [PDF]

open access: yesPLoS ONE, 2013
Pigmentation during insect development is a primal adaptive requirement. In the silkworm, melanin is the primary component of larval pigments. The rate limiting substrate in melanin synthesis is tyrosine, which is converted from phenylalanine by the rate-

Dynamic regulation of phenylalanine hydroxylase

open access: yesPteridines, 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
