Available in PDF, EPUB and Kindle. Book excerpt: Plant Nonprotein Amino and Imino Acids: Biological, Biochemical, and Toxicological Properties provides a comprehensive discussion of plant nonprotein amino acids. Much of this monograph is written with the neophyte in mind, thus necessitating the presentation of certain basic concepts that are well-known to the advanced worker. Rather than providing an exhaustive coverage of the subject matter, the book attempts to represent effectively the state of the art; to provide a helpful means of identifying and locating the pertinent literature; and to present the basic information necessary to encourage other workers to enter into the study of the nonprotein amino acids. The book begins with a review of nomenclature and physicochemical properties. This is followed by a discussion of analytical methods such as partition paper chromatography, thin-layer chromatography, ninhydrin color reaction, ion-exchange chromatography, and gas chromatography. Subsequent chapters deal with the toxicity of some nonprotein amino acids and their ability to exert debilitating effects in a host of organisms; and the intermediary metabolism of nonprotein amino acids.

This book was released on 1995-01-26 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: For 150 years scientists at the Rothamsted Experimental Station have studied aspects of plant nitrogen nutrition and amino acid biosynthesis. This book is the result of a meeting held to mark this century and a half of work there. The papers look at the significant progress in understanding the biochemistry of amino acids recently achieved, in the light of this history of research. Leading researchers from around the world have contributed authoritative chapters on protein amino acids, non-protein amino acids, betaines, glutathione, polyamines and other secondary metabolites derived from amino acids. As well as being essential in some animals' nutrition, these compounds can have important roles in defending against herbivores, insects and disease. An understanding of these compounds can help in devising better crop protection and production methods.

Available in PDF, EPUB and Kindle. Book excerpt: There is little wonder in the fact that the investigation of amino acids is of fundamental interest to scientists from so many diversified fields. If amino acids were only basic constituents of enzymes as well as structural and other proteins, this property alone would elevate them to real scientific importance. Added to this role, however, is their ability to serve as building blocks for the production of many classes of secondary metabolites. They can support the biosynthesis of a myriad of natural products including nonprotein amino acids, cyanogenic glycosides, phar macologically active alkaloids, certain phenols, purines and pyrimidines, nucleic acids, condensed tannins, lignins and other metabolites. The approximately twenty or so amino (and imino) acids that comprise proteins are well known; less familiar are what is now approaching 600 nonprotein amino acids that have been isolated and characterized from plant, fungal or animal sources. Investigations of the protein amino acids have proven of outstanding value in enhancing our understanding of a variety of physiological and neurological topics that affect human health and well being. Amino acids are used to probe inhibitory and excitatory transmission receptors in the brain. They contribute to our understanding of epilepsy, development of anti-epileptic drugs, production of novel y-arninobutyric acid uptake inhibitors, and acute and chronic neurodegenera tive disorders.

Download or read book The Nonprotein Amino Acid Meta tyrosine written by Tengfang Huang and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to the twenty amino acids that are universally found as building blocks of proteins, nonprotein amino acids are also present in numerous plant species. One such nonprotein amino acid, meta -tyrosine, is abundant in the root exudates of Chewings fescue (Festuca rubra L. ssp. commutata ). Consistent with the phytotoxic effects of mtyrosine, prior studies showed that Chewings fescue has superior weed-suppressive capacity in field trials involving dozens of turf grass varieties. Further research with m-tyrosine demonstrates that this compound is stored in a different compartment than the protein amino acids, and can be easily washed off fescue roots with aqueous solutions. Chewings fescue roots have enzymatic activity, likely from a cytochrome P450, for synthesizing m-tyrosine from phenylalanine. An EST library was constructed from roots of Chewings fescue and four candidate cytochrome P450 genes are identified and cloned. When added to A. thaliana growth medium, m-tyrosine can be misincorporated into A. thaliana proteins. Several protein amino acids, in particular phenylalanine, partially rescue the toxicity of m-tyrosine. Correspondingly, a screen for m-tyrosine resistance in A. thaliana identified a mutant that over-accumulates free phenylalanine. Map-based cloning showed that the genetic basis of this phenotype is a dt2-1D, a mutant allele of ADT2, which encodes arogenate dehydratase, the final enzyme of the phenylalanine biosynthesis pathway. Characterization of ADT2 and its mutant form revealed feed-back regulation of phenylalanine biosynthesis, which depends on a critical motif of the ADT2 protein. Overexpression of the feedback-insensitive a dt2- 1D produces even higher levels of free phenylalanine and has pleiotropic physiological consequences, including abnormal leaf development, resistance to 5methyltryptophan, reduced growth of the generalist lepidopteran herbivore Trichoplusia ni (cabbage looper), and increased salt tolerance. Finally, several hypotheses for m-tyrosine modes of action were tested and discussed.

Book excerpt: Amino acid biochemistry in plants has been a major topic research. There are many aspects of amino acid metabolism in plants that has to be understood. The biosynthesis and metabolic regulation of synthesis, of several protein amino acid still pose questions such as histidine synthesis, the regulation of methionine synthesis and proline metabolism which is dealt with in a limited way. Amino acid derived secondary metabolites are still rich field of biochemists and recent progress in understanding metabolisms is encouraging. Plants convert inorganic nitrogen into amino acids, the building blocks for proteins. They also make a wide range of other nitrogen compounds to help protect themselves from pests and diseases. An understanding of these compounds can therefore help in devising better crop protection and production methods. This volume contains essays by scientists who have studied aspects of plant nitrogen nutrition and amino acid biosynthesis. There are chapters on protein amino acids, nonprotein amino acids, betaines, glutathione, polyamines, and other secondary metabolites derived from amino acids. The results of these studies will be of interest to students and professionals in biochemistry and botany.

This book was released on 2012-12-06 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amino acids are featured in course syllabuses and in project and research work over a wide spectrum of subject areas in chemistry and biology. Chemists and biochemists using amino acids have many common needs when they turn to the literature for comprehensive information. Among these common interests, analytical studies, in particular, have undergone rapid development in recent years. All other chemical and biochemical aspects of amino acids - synthesis, properties and reactions, preparation of derivatives for use in peptide synthesis, racemization and other fundamental mechanistic knowledge - have been the subject of vigorous progress. This book offers a thorough treatment of all these developing areas, and is structured in the belief that biochemists, physiologists and others will profit from access to information on topics such as the physical chemistry of amino acid solutions, as well as from thorough coverage of amino acid metabolism, biosynthesis and enzyme inhibition; and that chemists will find relevant material in biological areas as well as in the analysis, synthesis and reactions of amino acids.
