Functioni

Catalytic activityi

L-phenylalanine + tetrahydrobiopterin + O2 = L-tyrosine + 4a-hydroxytetrahydrobiopterin.

Cofactori

Enzyme regulationi

N-terminal region of PAH is thought to contain allosteric binding sites for phenylalanine and to constitute an "inhibitory" domain that regulates the activity of a catalytic domain in the C-terminal portion of the molecule.

Pathwayi: L-phenylalanine degradation

This protein is involved in step 1 of the subpathway that synthesizes acetoacetate and fumarate from L-phenylalanine.
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. Phenylalanine-4-hydroxylase (PAH)
  2. Tyrosine aminotransferase (TAT)
  3. 4-hydroxyphenylpyruvate dioxygenase (HPD)
  4. Homogentisate 1,2-dioxygenase (HGD)
  5. Maleylacetoacetate isomerase (GSTZ1)
  6. Fumarylacetoacetase (FAH)
This subpathway is part of the pathway L-phenylalanine degradation, which is itself part of Amino-acid degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes acetoacetate and fumarate from L-phenylalanine, the pathway L-phenylalanine degradation and in Amino-acid degradation.

Pathology & Biotechi

Involvement in diseasei

Phenylketonuria (PKU)34 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAutosomal recessive inborn error of phenylalanine metabolism, due to severe phenylalanine hydroxylase deficiency. It is characterized by blood concentrations of phenylalanine persistently above 1200 mumol (normal concentration 100 mumol) which usually causes mental retardation (unless low phenylalanine diet is introduced early in life). They tend to have light pigmentation, rashes similar to eczema, epilepsy, extreme hyperactivity, psychotic states and an unpleasant 'mousy' odor.

Non-phenylketonuria hyperphenylalaninemia (Non-PKU HPA)5 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionMild form of phenylalanine hydroxylase deficiency characterized by phenylalanine levels persistently below 600 mumol, which allows normal intellectual and behavioral development without treatment. Non-PKU HPA is usually caused by the combined effect of a mild hyperphenylalaninemia mutation and a severe one.
See also OMIM:261600
Hyperphenylalaninemia (HPA)9 Publications
