Biopterin-dependent aromatic amino acid hydroxylase; a family of non-heme, iron(II)-dependent enzymes that includes prokaryotic and eukaryotic phenylalanine-4-hydroxylase (PheOH), eukaryotic tyrosine hydroxylase (TyrOH) and eukaryotic tryptophan hydroxylase (TrpOH). PheOH converts L-phenylalanine to L-tyrosine, an important step in phenylalanine catabolism and neurotransmitter biosynthesis, and is linked to a severe variant of phenylketonuria in humans. TyrOH and TrpOH are involved in the biosynthesis of catecholamine and serotonin, respectively. The eukaryotic enzymes are all homotetramers.

phenylalanine-4-hydroxylase, tetrameric form; This model describes the larger, tetrameric form of phenylalanine-4-hydroxylase, as found in metazoans. The enzyme irreversibly converts phenylalanine to tryosine and is known to be the rate-limiting step in phenylalanine catabolism in some systems. It is closely related to metazoan tyrosine 3-monooxygenase and tryptophan 5-monoxygenase, and more distantly to monomeric phenylalanine-4-hydroxylases of some Gram-negative bacteria. The member of this family from Drosophila has been described as having both phenylalanine-4-hydroxylase and tryptophan 5-monoxygenase activity (. However, a Drosophila member of the tryptophan 5-monoxygenase clade has subsequently been discovered.

Eukaryotic phenylalanine-4-hydroxylase (eu_PheOH); a member of the biopterin-dependent aromatic amino acid hydroxylase family of non-heme, iron(II)-dependent enzymes that also includes prokaryotic phenylalanine-4-hydroxylase (pro_PheOH), eukaryotic tyrosine hydroxylase (TyrOH) and eukaryotic tryptophan hydroxylase (TrpOH). PheOH catalyzes the first and rate-limiting step in the metabolism of the amino acid L-phenylalanine (L-Phe), the hydroxylation of L-Phe to L-tyrosine (L-Tyr). It uses (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) as the physiological electron donor. The catalytic activity of the tetrameric enzyme is tightly regulated by the binding of L-Phe and BH4 as well as by phosphorylation. Mutations in the human enzyme are linked to a severe variant of phenylketonuria.

phenylalanine-4-hydroxylase, monomeric form; This model describes the smaller, monomeric form of phenylalanine-4-hydroxylase, as found in a small number of Gram-negative bacteria. The enzyme irreversibly converts phenylalanine to tryosine and is known to be the rate-limiting step in phenylalanine catabolism in some systems. This family is of biopterin and metal-dependent hydroxylases is related to a family of longer, multimeric aromatic amino acid hydroxylases that have additional N-terminal regulatory sequences. These include tyrosine 3-monooxygenase, phenylalanine-4-hydroxylase, and tryptophan 5-monoxygenase. [Energy metabolism, Amino acids and amines]

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
