General annotation (Comments)

Catalytic activity

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

Cofactor

Fe2+ ion.

Enzyme regulation

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.

Pathway

Amino-acid degradation; L-phenylalanine degradation; acetoacetate and fumarate from L-phenylalanine: step 1/6.

Subunit structure

Homodimer and homotetramer. Ref.4

Post-translational modification

Phosphorylation at Ser-16 increases basal activity and facilitates activation by the substrate phenylalanine By similarity.

Sequence similarities

Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.

Contains 1 ACT domain.
