A Phenylalanine Ammonia Lyase Capacitive Sensor for Phenylalanine Detection

open access: yesProceedings
In this paper, an easy-to-use and fast biosensor for phenylalanine quantification in patients affected by phenylketonuria is investigated. The phenylalanine concentration was indirectly estimated through the ammonia released as a by-product of an ...

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.

Phenylalanine Ammonia-lyase of Bamboo Shoots [PDF]

open access: yesAgricultural and Biological Chemistry, 1988
Phenylalanine ammonia-lyase (PAL) was purified from bamboo shoots (Bambusa oldhami Munro) through steps of DEAE-Sephacel column chromatography, Sepharose CL-6B gel filtration, and a second DEAE-Sephacel column chromatography. Polyacrylamide gel electrophoresis showed that the purified enzyme (Mr 360, 000) still contained two minor bands with much ...

Erythrocytes as Carriers of Therapeutic Enzymes. [PDF]

open access: yes, 2020
Therapeutic enzymes are administered for the treatment of a wide variety of diseases. They exert their effects through binding with a high affinity and specificity to disease-causing substrates to catalyze their conversion to a non-noxious product, to ...

Maize Phenylalanine Ammonia-Lyase Has Tyrosine Ammonia-Lyase Activity [PDF]

open access: yesPlant Physiology, 1997
Abstract A full-length cDNA encoding phenylalanine ammonia-lyase (PAL) from Zea mays L. was isolated and the coding region was expressed in Escherichia coli as a C-terminal fusion to glutathione S-transferase. After purification by glutathione-Sepharose chromatography, the glutathione S-transferase moiety was cleaved off and the ...

The effectiveness of plant hydrocolloids at maintaining the quality characteristics of the encapsulated form of L-phenylalanine-ammonia-lyase

open access: yesHeliyon, 2020
The effect of three types of polysaccharides (agar-agar, carrageenan, hydroxypropyl methylcellulose) on the activity and stability during storage at given temperature conditions of the enzyme preparation L-phenylalanine ammonia-lyase was studied.

Molecular genetics of naringenin biosynthesis, a typical plant secondary metabolite produced by Streptomyces clavuligerus [PDF]

open access: yes, 2015
Background: Some types of flavonoid intermediates seemed to be restricted to plants. Naringenin is a typical plant metabolite, that has never been reported to be produced in prokariotes.

Changes in phenols composition and activity of phenylalanine-ammonia lyase in apples after fungal infections

open access: yesHorticultural Science, 2011
The defensive reaction of apple cultivar Idared (Malus domestica Borkh.) was studied after inoculation with three different pathogens (Penicillium expansum, Monilinia fructigena, and Gloeosporium spp.).

ENDOPHYTIC BACTERIA ASSOCIATED WITH SUGARCANE AND ITS POTENTIAL TO SUPPRESS SPORISORIUM SCITAMINEUM, THE CAUSAL FUNGAL PATHOGEN OF SMUT DISEASE [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2019
Bacterial endophytic ubiquitously colonize the internal tissues of the plant. The purpose of this study was to isolate and identify the endophytic bacteria from sugarcane stalks which have antagonistic activity against Sporisorium scitamineum, the causal
