Phenylalanine hydroxylase. (PAH) (EC 1.14.16.1) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine. PAH is one of three members of the biopterin-dependent aromatic amino acid hydroxylases, a class of monooxygenase that uses … Zobraziť viac The reaction is thought to proceed through the following steps: 1. formation of a Fe(II)-O-O-BH4 bridge. 2. heterolytic cleavage of the O-O bond to yield the ferryl oxo hydroxylating intermediate … Zobraziť viac The PAH monomer (51.9 kDa) consists of three distinct domains: a regulatory N-terminal domain (residues 1–117) that contains a Phe-binding ACT subdomain, the catalytic domain (residues 118–427), and a C-terminal domain (residues 428–453) … Zobraziť viac Deficiency in PAH activity due to mutations in PAH causes hyperphenylalaninemia (HPA), and when blood phenylalanine levels increase above 20 times the normal concentration, the metabolic disease phenylketonuria (PKU) results. PKU is … Zobraziť viac Phenylalanine hydroxylase is closely related to two other enzymes: • tryptophan hydroxylase (EC number 1.14.16.4), which controls levels of serotonin in the brain and the gastrointestinal tract • tyrosine hydroxylase (EC number … Zobraziť viac PAH is proposed to use the morpheein model of allosteric regulation.
