Liver phenylalanine hydroxylase assay [PDF]
The first reaction is catalyzed by phenylalanine hydroxylase and the second reaction, which generates the reduced form of pteridine cofactor (biopterin), is catalyzed by dihydropteridine reductase (l-3). A direct assay of phenylalanine hydroxylase can be achieved by supplying optimal concentrations of reduced pteridine cofactor or an analog of the ...

Liver phenylalanine hydroxylase is allosterically activated by phenylalanine. The structural changes that accompany activation have not been identified, but recent studies of the effects of phenylalanine on the isolated regulatory domain of the enzyme ...

ThiF‐Like Enzyme Chemistry in Primary and Secondary Metabolism
ThiF‐like enzymes are a widespread protein family found in disparate biosynthetic pathways. They are unified by their use of an NTP to modify a carboxylate, generating an activated species prone to nucleophilic addition. This common intermediate is then targeted by diverse nucleophiles, including persulfide or amino acid side chains, to yield a variety

Inherited metabolic epilepsies–established diseases, new approaches
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Hyperphenylalaninemia and serotonin deficiency in Dnajc12-deficient mice
Serotonin exerts numerous neurological and physiological actions in the brain and in the periphery. It is generated by two different tryptophan hydroxylase enzymes, TPH1 and TPH2, in the periphery and in the brain, respectively, which are members of the ...

Recommendations for the nutrition management of phenylalanine hydroxylase deficiency
The effectiveness of a phenylalanine-restricted diet to improve the outcome of individuals with phenylalanine hydroxylase deficiency (OMIM no. 261600) has been recognized since the first patients were treated 60 years ago.

Metabolic syndrome is characterized by abdominal obesity, hyperglycemia, dyslipidemia, and hypertension. Bioactive compounds extracted from herbs, tea, and coffee using microbial cell factories, particularly resveratrol and caffeic acid, have demonstrated remarkable potential in the management of metabolic syndrome, offering innovative solutions for ...
