Synthesis and degradation of phenylalanine ammonia-lyase of Rhodosporidium toruloides [PDF]

open access: yesJournal of Bacteriology, 1982
The regulation of the enzyme phenylalanine ammonia-lyase (PAL), which is of potential use in oral treatment of phenylketonuria, was investigated. Antiserum against PAL was prepared and was shown to be monospecific for the enzyme by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

IMMOBILIZATION OF PHENYLALANINE AMMONIA-LYASE ON HYDROXYAPATITE AND HYDROXYAPATITE COMPOSITES

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2021
A new and efficient immobilization method of phenylalanine ammonia-lyase was obtained using hydroxyapatite (HAP) and hydroxyapatite - carbon nanotube, gelatin and chitosan - composites (HAP-CNT, HAP-GEL and HAP-CS) as support material.

Fluorescent enzyme-coupled activity assay for phenylalanine ammonia-lyases [PDF]

open access: yesScientific Reports, 2020
AbstractPhenylalanine ammonia-lyases (PALs) catalyse the non-oxidative deamination of l-phenylalanine to trans-cinnamic acid, while in the presence of high ammonia concentration the reverse reaction occurs. PALs have been intensively studied, however, their industrial applications for amino acids synthesis remained limited, mainly due to their ...

Sustainable synthesis of L-phenylalanine derivatives in continuous flow by immobilized phenylalanine ammonia lyase

open access: yesFrontiers in Catalysis, 2023
The application of phenylalanine ammonia lyases (PALs) for the amination of a variety of cinnamic acids has been shown to be a cost-efficient method to produce a variety of phenylalanine analogues.

SP3 and DEP1 Orchestrate Panicle Architecture by Jointly Regulating APO2 Expression in Rice

open access: yesAdvanced Science, EarlyView.
The transcription factor SP3 enhances inflorescence meristem activity and interacts with the cysteine‐rich domain of DEP1. This interaction alters DEP1's subcellular localization between the plasma membrane and nucleus, and suppresses SP3‐mediated transcriptional activation of APO2.

In Vivo Biosynthesis and Direct Incorporation of Noncanonical Amino Acids into Proteins

open access: yesChemBioChem, EarlyView.
This review evaluates engineered (semi)autonomous cell systems for the biosynthesis and incorporation of noncanonical amino acids (ncAAs) into proteins. While semi‐autonomous cells convert supplied precursors into ncAAs autonomous cells integrate biosynthetic pathways that produce these building blocks intracellularly.

Seizures and electroencephalographic findings in inborn errors of metabolism: Clues to differential diagnosis in the neonatal period, infancy, childhood and adolescence, and review of the literature

open access: yesEpileptic Disorders, EarlyView.
Abstract Although inborn errors of metabolism (IEM) are a rare cause of epilepsy, seizures are a common presentation in these disorders. Seizures in IEM are frequently refractory to conventional anti‐seizure medication and might warrant initiation of specific treatments based on vitamins or dietary modifications or provision of alternative substrates ...

Stepwise Simulation of 3,5-Dihydro-5-methylidene-4H-imidazol-4-one (MIO) Biogenesis in Histidine Ammonia-lyase [PDF]

open access: yes, 2016
A 3,5-dihydro-5-methylidene-4H-imidazol-4-one (MIO) electrophilic moiety is post-translationally and autocatalytically generated in homotetrameric histidine ammonia-lyase (HAL) and other enzymes containing the tripeptide Ala-Ser-Gly in a suitably ...
