Catecholamines 226-240 phenylalanine hydroxylase Homo sapiens 281-306 12631267-8 2003 Two alternative conformations, rotated 180 degrees around an imaginary iron-catecholamine axis, were found for DA and l-DOPA in PAH and for DA in TH. Catecholamines 76-89 phenylalanine hydroxylase Homo sapiens 128-131 33336311-3 2020 Hypo/hypercapnia, as well as mechanical ventilation during and after resuscitation, can affect CO2 levels and trigger a dangerous pathophysiological vicious circle related to the relationship between pH, cellular demand, and catecholamine levels. Catecholamines 225-238 phenylalanine hydroxylase Homo sapiens 200-202 1959929-5 1991 The regions that have been found to be linked to TSC in different families map to the positions of three enzymes, phenylalanine hydroxylase (12q22-24), tyrosinase (11q14-22), and dopamine-beta-hydroxylase (9q34), all of which are involved in the conversion of phenylalanine to catecholamine neurotransmitters or melanin. Catecholamines 277-290 phenylalanine hydroxylase Homo sapiens 114-139 34952194-1 2022 Phenylalanine hydroxylase (PAH) is involved in immune defence reactions by providing the starting material, tyrosine, to synthesise catecholamines and melanin. Catecholamines 132-146 phenylalanine hydroxylase Homo sapiens 0-25 34952194-1 2022 Phenylalanine hydroxylase (PAH) is involved in immune defence reactions by providing the starting material, tyrosine, to synthesise catecholamines and melanin. Catecholamines 132-146 phenylalanine hydroxylase Homo sapiens 27-30 2872999-1 1986 Phenylalanine hydroxylase (PAH) and tyrosine hydroxylase (TH) are consecutive enzymes in the metabolic pathway leading to the production of catecholamine neurotransmitters. Catecholamines 140-153 phenylalanine hydroxylase Homo sapiens 0-25 2872999-1 1986 Phenylalanine hydroxylase (PAH) and tyrosine hydroxylase (TH) are consecutive enzymes in the metabolic pathway leading to the production of catecholamine neurotransmitters. Catecholamines 140-153 phenylalanine hydroxylase Homo sapiens 27-30 5165490-0 1971 Two mechanisms for the inhibition in vitro of phenylalanine hydroxylase by catecholamines. Catecholamines 75-89 phenylalanine hydroxylase Homo sapiens 46-71 32929770-13 2021 CONCLUSION: We introduced a method that can resolve Pi using 7 Tesla STEAM 31 P-MRS. We demonstrate the stability of Pi/PCr and myocardial pH in volunteers at rest and during catecholamine stress. Catecholamines 175-188 phenylalanine hydroxylase Homo sapiens 139-141 26241318-4 2015 These solution properties are consistent with the regulatory mechanisms of the two enzymes, in that phenylalanine hydroxylase is activated by phenylalanine binding to an allosteric site, while tyrosine hydroxylase is regulated by binding of catecholamines in the active site. Catecholamines 241-255 phenylalanine hydroxylase Homo sapiens 100-125 21839840-8 2011 These results indicated collectively that CfPAH, as a homologue of phenylalanine hydroxylase in scallop C. farreri, could be induced by cytokine and involved in the immunomodulation of scallops by supplying the starting material tyrosine for the synthesis of melanin and catecholamines. Catecholamines 271-285 phenylalanine hydroxylase Homo sapiens 67-92 23898865-1 2013 BACKGROUND: Phenylalanine hydroxylase (PAH) is the enzyme that metabolizes phenylalanine, an essential amino acid required for catecholamine synthesis. Catecholamines 127-140 phenylalanine hydroxylase Homo sapiens 12-37 23898865-1 2013 BACKGROUND: Phenylalanine hydroxylase (PAH) is the enzyme that metabolizes phenylalanine, an essential amino acid required for catecholamine synthesis.
