Voltammetric Determination of Phenylalanine Using Chemically Modified Screen-Printed Based Sensors

open access: yesChemosensors, 2020
This paper describes the sensitive properties of screen-printed carbon electrodes (SPCE) modified by using three different electroactive chemical compounds: Meldola’s Blue, Cobalt Phthalocyanine and Prussian Blue, respectively.

Investigation of the relationship between phenylalanine in venous plasma and capillary blood using volumetric blood collection devices

open access: yesJIMD Reports, 2023
Measurement of plasma and dried blood spot (DBS) phenylalanine (Phe) is key to monitoring patients with phenylketonuria (PKU). The relationship between plasma and capillary DBS Phe concentrations has been investigated previously, however, differences in ...

The metabolism of phenylalanine.

open access: yes, 1966
The metabolism of phenylalanine-C14 was studied in three different groups of rats: normal animals, phenylalanine-deficient animals and rats which had been maintained on a high (5 and 7%) phenylalanine diet from 21 days of age and considered to be ...

Amino acid-incorporated polymer network by thiol-ene polymerization

open access: yeseXPRESS Polymer Letters, 2015
Triallyl L-alanine (A3A) and triallyl L-phenylalanine (A3F) were synthesized by reactions of L-alanine and L-phenylalanine with allyl bromide in the presence of sodium hydroxide, respectively.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Phenylalanine and Tyrosine as Exogenous Precursors of Wheat (Triticum aestivum L.) Secondary Metabolism through PAL-Associated Pathways

open access: yesPlants, 2020
Reacting to environmental exposure, most higher plants activate secondary metabolic pathways, such as the metabolism of phenylpropanoids. This pathway results in the formation of lignin, one of the most important polymers of the plant cell, as well as a ...

STIMULATION OF GROWTH AND OIL PRODUCTION IN CUMIN PLANT [PDF]

open access: yesScientific Journal of Flowers and Ornamental Plants, 2020
A pot experiment was carried out during two successive seasons (2017/ 2018 and 2018/2019) at Medicinal and Aromatic Plants Research Department in Dokki. The aim of this work was to study the effect of foliar application of phenylalanine (Phe) and p < /em>
