Phenylalanine ammonia-lyase - Wikipedia
Phenylalanine ammonia lyase (EC 4.3.1.24) is an enzyme that catalyzes a reaction converting L-phenylalanine to ammonia and trans-cinnamic acid. Phenylalanine ammonia lyase (PAL) is the first and committed step in the phenyl propanoid pathway and is therefore involved in the biosynthesis of the polyphenol compounds such as flavonoids, phenylpropanoids, and lignin in plants. Phenylalanine ammonia lyase is found widely in plants, as well as some yeast and fungi, with isoenzymes existing within many different species. It has a molecular mass in the range of 270-330 kDa. The activity of PAL is induced dramatically in response to various stimuli such as tissue wounding, pathogenic attack, light, low temperatures, and hormones. PAL has recently been studied for possible therapeutic benefits in humans afflicted with phenylketonuria. It has also been used in the generation of L-phenylalanine as precursor of the sweetener aspartame. The enzyme is a member of the ammonia lyase family, which cleaves ...
Zymophore identification enables the discovery of novel phenylalanine ammonia lyase enzymes | Research Explorer | The...
The suite of biological catalysts found in Nature has the potential to contribute immensely to scientific advancements, ranging from industrial biotechnology to innovations in bioenergy and medical intervention. The endeavour to obtain a catalyst of choice is, however, wrought with challenges. Herein we report the design of a structure-based annotation system for the identification of functionally similar enzymes from diverse sequence backgrounds. Focusing on an enzymatic activity with demonstrated synthetic and therapeutic relevance, five new phenylalanine ammonia lyase (PAL) enzymes were discovered and characterised with respect to their potential applications. The variation and novelty of various desirable traits seen in these previously uncharacterised enzymes demonstrates the importance of effective sequence annotation in unlocking the potential diversity that Nature provides in the search for tailored biological tools. This new method has commercial relevance as a strategy for assaying the ...

Phenylpropanoids metabolism - Wikipedia
The metabolic pathway of phenylpropanoids involves a number of enzymes. The shikimate pathway is a seven step metabolic route used by bacteria, fungi, and plants for the biosythesis of aromatic amino acids (phenylalanine, tyrosine, and tryptophan). In plants, the biosynthesis of all phenylpropanoids begins with the amino acids phenylalanine and tyrosine. Phenylalanine ammonia-lyase (PAL, a.k.a. phenylalanine/tyrosine ammonia-lyase) is an enzyme responsible for the transformation of L-phenylalanine or tyrosine into trans-cinnamic acid or p-coumaric acid respectively and ammonia. Trans-cinnamate 4-monooxygenase (cinnamate 4-hydroxylase) is the enzyme responsible for the transformation of trans-cinnamate into 4-hydroxycinnamate (p-coumaric acid). 4-Coumarate-CoA ligase is the enzyme responsible for the transformation of 4-coumarate (p-coumaric acid) into 4-coumaroyl-CoA. Cinnamyl-alcohol dehydrogenase (CAD), an enzyme responsible for the transformation of cinnamyl alcohol into cinnamaldehyde ...

Selection of Differentially Expressed Genes Using the Transcriptome Analysis of Ripening Grape Berries in Response to High...
Findings: Functional categorization of expressed transcripts revealed the conservation of genes involved in various biological processes like responses to chemical (12.7%), responses to abiotic stimulus (11.8%), biosynthesis processes (11.8%), and cellular metabolic processes (10.4%) in grape berries exposed to high temperature. The major up-regulated genes included isocitratelyase, cysteine proteinases superfamily protein, cupin family protein, and glycosyl hydrolase genes, and the major down-regulated genes included flavanone 3-hydroxylase, phenylalanine ammonia lyase, chlorophyll A-B binding family protein, and polygalacturonase inhibiting protein genes in grape berries exposed to high temperature. Among genes related to grape coloration, expressions of chalcone and stilbene synthase, flavanone 3-hydroxylase, leucoanthocyanidin dioxygenase, phenylalanine ammonia lyasegenes were more strongly inhibited in berries kept at 35°C than 25°C.. ...
buy Zarnestra - Novel targets for Alzheimers disease treatment
Supplementary MaterialsSupplemental Data 1. mobile machinery Bmp6 necessary for proteins folding, disulfide relationship development, glycosylation, and quality control takes on an essential part in planning precursors for transit with the secretory pathway. The production of product peptides requires the participation of multiple proteases frequently. Amidation from the COOH-terminus of the peptide, that is frequently needed for biological activity, requires the participation of peptidylglycine bond in glycine, producing amidated peptide plus glyoxylate. When expressed individually, both catalytic domains of buy Zarnestra PAM are active, and each is efficiently stored in secretory granules. Although this finding suggests that PHM and PAL activities do not need to be encoded by the same gene, species ranging from human to suggests that this enzyme has an ancient role in detecting and responding to environmental stimuli. PAM requires molecular oxygen along with ascorbate, copper, and zinc, and ...
A PAL1 gene promoter-green fluorescent protein reporter system to analyse defence responses in live cells of Arabidopsis...
Arabidopsis thaliana ecotype Columbia-0 was transformed with a green fluorescent protein (GFP) gene under control of a phenylalanine ammonia-lyase (PAL) promoter. PAL is a key enzyme of the phenylpropanoid pathway and is induced to high levels during plant stress. Constitutive expression of PAL1 promoter-controlled GFP occurred in vascular tissues within stems, leaves and roots and in developing flowers. PAL1 promoter-GFP expression was examined in leaves of transgenic plants subjected to an abiotic elicitor, mechanical wounding or to inoculation with the pathogens Pseudomonas syringae pv. tomato or Peronospora parasitica. Wounding of leaves and treatment with an abiotic elicitor and compatible interactions produced low to moderate levels of GFP. However, in incompatible interactions there were high levels of GFP produced. In incompatible interactions, the intensity of GFP fluorescence was similar to that produced in transgenic plants expressing GFP driven by the CaMV promoter. The bright green ...

Last Gas For 200 Miles: November 2008
The particular ground wed drawn were three subdivisions, not all that different in character from those on my youth back in suburban Cleveland and Detroit. Its usually easy to determine whether this was recently-sold farm acreage or not by whether the land across the road still has corn on it or not. This one was new enough, though, one where the model homes have names like Concord, Belvedere, Bay View, Newport and Bella Vista. (Do these actually mean anything?) It was the way the middle one began petering out that belied the waving banners and few balloons and the whole showroom atmosphere. Out at the fringes, it was little more than gravel pits and mounds as cement road curves around leveled lots overgrown with weeds before a line of trees; you could also note landscapers earth-moving equipment betraying signs of rust and a couple of empty contractors trailers.

To assess nickel-induced toxicity in plants, Zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 50-200 μM for a period of two weeks. Observed biological makers included biomass, soluble and total protein contents, and the activities of guaiacol peroxidase (GPX), ascorbate peroxidase (APX), catalase (CAT), and phenylalanine ammonia-lyase (PAL) in the leaves and roots of maize. The fresh and dry weight of leaves and roots increased in 50 μM nickel but decreased in 100 and 200 μM. Soluble and total protein contents were significantly increased by increasing nickel concentrations up to 200 μM nickel in both roots and leaves of maize. Significant increases of ascorbate peroxidase (the highest activity at 200 μM nickel), catalase (the highest activity at 50 μM nickel), and phenylalanine ammonia-lyase (the highest activity at 100 μM nickel) were observed in the leaves and roots of Zea mays seedlings at all tested nickel concentrations.

Proline biosynthesis in plants stimulates the pentose phosphate pathway which results in an increasing carbon flux through the shikimate pathway. Shikimate pathway supplies carbon structures for many secondary metabolic pathways in plants. Chorismate, which is the end product of the shikimate pathway, becomes the branch point for the synthesis of phenylpropanoid and anthraquinones (AQs) in Rubia tinctorum secondary metabolism. We tested the effect of proline addition in plant suspension cultures of R. tinctorum in order to study the competition between the two above mentioned secondary metabolic pathways. Suspension cultures were treated with proline at different concentrations 0.25, 5 and 25 mM. Low proline level (0.25mM) produced an increase on AQs (50%) while high levels of proline ( 5 and 25 mM) showed a significant decrease on AQs accumulation ( 35 % an 50 %) and an increase in phenolics concentration. The increase on phenolic acids content was preceded by an induction on PAL activity. ...

Deterioração pós-colheita da mandioca minimamente processada
The roots of cassava present high postharvest perishability due to physiological deterioration that develops in wounded tissues usaully within two to three days after harvest at room temperature. The physiological deterioration is characterized by the appearance of blue-black streaks in the root vascular tissue and storage parenchyma, which progresses through the whole length of the root, being the initial cause for the poor acceptability for fresh consumption. This darkening is attributed to reactions involving the enzymes phenylalanine ammonia lyase, polyphenol oxidase and peroxidase. The objective of this work was to evaluate the effects biochemical, physiological and physical phases by the called minimal processing, the use of antioxidants and of packaging on the development of physiological deterioration in cassava roots during a period of preservation, in order to extend the shelf-life of the product, as well as to ensure food safety during the commercialization, distribution and ...

Isolation and analysis of cinnamic acid 4-hydroxylase homologous genes by S. Kawai, A. Mori et al.
Cinnamic acid 4-hydroxylase (CA4H) is the second enzyme involved in phenylpropanoid biosynthesis and is a member of the cytochrome P-450 superfamily. Three CA4H homologous genes, cyp73a, cyp73b, and cyp73c, and a cDNA clone of cyp73a were isolated from a genomic library and a cDNA library of a hybrid aspen; Populus kitakamiensis, and were characterized. They might be interrupted by two introns each. cyp73a and cyp73b were very similar to each other not only in coding regions but also in non-coding regions. Southern blot analysis showed that four homologous genes for CA4H constructed a small gene family in the diploid genome of P. kitakamiensis. In the promoter regions, there were many common cis-element-like sequences in phenylpropanoid biosynthesis genes.
Phenylpropanoids (Inhibitors Agonists Modulators Antagonists)-MedChemExpress.com
The phenylpropanoids are a diverse family of organic compounds that are synthesized by plants from the amino acids phenylalanine and tyrosine. Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of cinnamic acid, which is synthesized from phenylalanine in the first step of phenylpropanoid biosynthesis. Phenylpropanoids are found throughout the plant kingdom, where they serve as essential components of a number of structural polymers, provide protection from ultraviolet light, defend against herbivores and pathogens, and mediate plant-pollinator interactions as floral pigments and scent compounds. Concentrations of phenylpropanoids within plants are also altered by changes in resource availability.. ...
Showing Compound L-(-)-Phenylalanine (FDB004940) - FooDB
L-phenylalanine, also known as phe or f, belongs to phenylalanine and derivatives class of compounds. Those are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-phenylalanine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-phenylalanine can be found in watermelon, which makes L-phenylalanine a potential biomarker for the consumption of this food product. L-phenylalanine can be found primarily in most biofluids, including sweat, blood, urine, and cerebrospinal fluid (CSF), as well as throughout all human tissues. L-phenylalanine exists in all living species, ranging from bacteria to humans. In humans, L-phenylalanine is involved in a couple of metabolic pathways, which include phenylalanine and tyrosine metabolism and transcription/Translation. L-phenylalanine is also involved in few metabolic ...

Research | Albright College
Phenylpropanoid biosynthesis is an important component of plant secondary metabolism that has been extremely well characterized at the genetic, biochemical, and molecular levels. Research interest has been spurred by the importance of the endproducts in such diverse functions as flower pigmentation, UV protection, signaling (including regulation of auxin transport), male fertility, and defense against pathogens as well as their anti-oxidant and anti-cancer properties in humans. The pathway also offers a highly tractable genetic system that is characterized by easily-identifiable (i.e., flower, seed, or leaf color), non-lethal mutations that factored into Mendels elucidation of heritable traits, McClintocks work on transposable elements, and the discovery of cosuppression. Extensive molecular, biochemical, and physiological characterization of this pathway and its many branches make it an ideal system in which to begin to address fundamental questions about Arabidopsis systems biology..

Description
To develop our project even further beyond the lab bench, we have a few objectives. It is particularly important to reach the highest expression levels possible for both of the approaches - PAL enzyme and polyphe proteins. Also, both of these systems (PAL and polyphe proteins), working in cooperation in one cell, could undoubdtedly become the most succesful approach and reach the maximum effectiveness. This would maximize the amount of phenylalanine uptaken from the human intestine into the probiotic bacteria. Read more about maximum system efficiency on our modelling page.. Another significant issue is safety and system regulation. One of the main reasons, why such probiotic bacteria might be prohibited to use, is continous fear of genetically modified organisms (GMOs) and their manipulation. In the view of the fact that our bacteria, in theory, would be used directly by people and could possibly cause medical issues, it is of great importance to regulate its life cycle and activity.

DED-resistant American elms
Saving the American Elm by Bruce Carley http://www.elmpost.org I have posted this article to call attention to a special project which I have been doing since 1994 and which hopefully will be a source of inspiration for many. Ever since some new disease-resistant varieties of purely American elm were called to my attention, I have been hooked on raising these trees for distribution in my home town of Acton, Massachusetts, and it did not take me long to conceive of finding a way to have them planted on various conservation lands, where they will always be safe from indifferent landowners. I soon became acquainted with this town s conservation director, who welcomed my idea wholeheartedly and gave me the necessary permission. During their usual strolls along the main streets of their home towns, our parents and grandparents gazed at the scenery around them and took for granted a spectacular picture that is seldom observed nowadays and that few of us can hope to see during our lifetimes.
