PAH, also known as Phenylalanine-4-hydroxylase , Phe-4-monooxygenase, and encoded by the gene name PAH, belongs to the biopterin-dependent aromatic amino acid hydroxylase family. Phenylalanine hydroxylase is the rate-limiting enzyme of the metabolic pathway that degrades excess phenylalanine. Phenylalanine hydroxylase (PheOH, alternatively PheH or PAH) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine. PheOH is one of three members of the pterin-dependent amino acid hydroxylases, a class of monooxygenase that uses tetrahydrobiopterin (BH4, a pteridine cofactor) and a non-heme iron for catalysis. During the reaction, molecular oxygen is heterolytically cleaved with sequential incorporation of one oxygen atom into BH4 and phenylalanine substrate. PAH has been associated with Phenylketonuria PKU, an autosomal recessive inborn error of phenylalanine metabolism, due to severe phenylalanine hydroxylase deficiency. Additioanlly, PAH has been associated with Non-phenylketonuria hyperphenylalaninemia (Non-PKU HPA), a mild form of phenylalanine hydroxylase deficiency characterized by phenylalanine levels persistently below 600 mumol, which allows normal intellectual and behavioral development without treatment. Finally, PAH may play a role in the Hyperphenylalaninemia (HPA), a mildest form of phenylalanine hydroxylase deficiency. PAH is broadly expressed, with greatest levels in skeletal muscle followed by heart, brain, pancreas and testis.
