Mapping the Severity of Phenylalanine Hydroxylase Deficiency. [PDF]
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]
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]
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 ...

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