IMMOBILIZATION OF PHENYLALANINE AMMONIA-LYASE ON HYDROXYAPATITE AND HYDROXYAPATITE COMPOSITES

Studia 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.

Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...

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

, 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.

Molecular phenotyping of the pal1 and pal2 mutants of Arabidopsis thaliana reveals far-reaching consequences on phenylpropanoid, amino acid, and carbohydrate metabolism [PDF]

, 2004
The first enzyme of the phenylpropanoid pathway, Phe ammonia-lyase (PAL), is encoded by four genes in Arabidopsis thaliana. Whereas PAL function is well established in various plants, an insight into the functional significance of individual gene family ...

Association of immune response with efficacy and safety outcomes in adults with phenylketonuria administered pegvaliase in phase 3 clinical trials [PDF]

, 2018
Background: This study assessed the immunogenicity of pegvaliase (recombinant Anabaena variabilis phenylalanine [Phe] ammonia lyase [PAL] conjugated with polyethylene glycol [PEG]) treatment in adults with phenylketonuria (PKU) and its impact on safety ...

Preparation of bioimprinting cross-linked enzyme aggregates of phenylalanine ammonia lyase and it's partial properties

Journal of Hebei University of Science and Technology, 2015
Phenylalanine ammonia lyase (PAL) is a key enzyme for production of L-phenylalanine. Currently, PAL is mainly obtained from Rhodotorula PAL However, Rhodotorula PAL exhibits poor stability, which limits its industrial application.

Nanogram amounts of salicylic acid produced by the rhizobacterium Pseudomonas aeruginosa 7NSK2 activate the systemic acquired resistance pathway in bean [PDF]

, 1999
Root colonization by specific nonpathogenic bacteria can induce a systemic resistance in plants to pathogen infections. In bean, this kind of systemic resistance can be induced by the rhizobacterium Pseudomonas aeruginosa 7NSK2 and depends on the ...

Defensive reactions of apple cultivars Angold and HL 1834 after fungal infection

Horticultural Science, 2011
Apple cultivars (Malus domestica Borkh.) were inoculated with a significant apple fruit fungal pathogen, Monilinia fructigena Honey ex Whetzel. Defensive reactions, especially enzyme activity and production of phenolic compounds, were compared.

Biochemical analysis ofCentaurea depressaphenylalanine ammonia lyase (PAL) for biotechnological applications in phenylketonuria (PKU) [PDF]

Pharmaceutical Biology, 2016
Phenylketonuria (PKU) is the most common hereditary defect of phenylalanine hydroxylase (PAH) enzyme achieving the hydroxylation of phenylalanine (Phe). Phenylalanine ammonia lyase (PAL) converts Phe to a harmless metabolite, trans-cinnamic acid (TCA) in plants and PAL enzyme activity is fairly high in plants rich in flavonoids.The study aimed the ...

Effect of natural PAL-enzyme on the quality of egg white and mushroom flour and study its impact on the expression of PKU related genes and phenylalanine reduction in mice fed on

Journal of Genetic Engineering and Biotechnology, 2017
PKU patients react to therapy with a low phenylalanine diet, but adherence to this diet is troublesome, subsequently the expansion of alternative ways is demand.
