  • 1 AMINO ACIDS Commonly, 21 L-Amino Acids Encoded by DNA Represent the Building Blocks of Animal, Plant, and Microbial Proteins
    1 AMINO ACIDS Commonly, 21 L-amino acids encoded by DNA represent the building blocks of animal, plant, and microbial proteins. The basic amino acids encountered in proteins are called proteinogenic amino acids 1.1). Biosynthesis of some of these amino acids proceeds by ribosomal processes only in microorganisms and plants and the ability to synthesize them is lacking in animals, including human beings. These amino acids have to be obtained in the diet (or produced by hydrolysis of body proteins) since they are required for normal good health and are referred to as essential amino acids. The essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The rest of encoded amino acids are referred to as non-essential amino acids (alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine). Arginine and histidine are classified as essential, sometimes as semi-essential amino acids, as their amount synthesized in the body is not sufficient for normal growth of children. Although it is itself non-essential, cysteine (classified as conditionally essential amino acid) can partly replace methionine, which is an essential amino acid. Similarly, tyrosine can partly replace phenylalanine. 1.1 The glutamic acid group 1.1.1 Glutamic acid and glutamine Free ammonium ions are toxic to living cells and are rapidly incorporated into organic compounds. One of such transformations is the reaction of ammonia with 2-oxoglutaric acid from the citric acid cycle to produce L-glutamic acid. This reaction is known as reductive amination. Glutamic acid is accordingly the amino acid generated first as both constituent of proteins and a biosynthetic precursor.

  • Characterization of a Second Secologanin Synthase Isoform

BMC Genomics (2015) 16:619 DOI 10.1186/s12864-015-1678-y RESEARCH ARTICLE Open Access Characterization of a second secologanin synthase isoform producing both secologanin and secoxyloganin allows enhanced de novo assembly of a Catharanthus roseus transcriptome Thomas Dugé de Bernonville1†, Emilien Foureau1†, Claire Parage1†, Arnaud Lanoue1, Marc Clastre1, Monica Arias Londono1,2, Audrey Oudin1, Benjamin Houillé1, Nicolas Papon1, Sébastien Besseau1, Gaëlle Glévarec1, Lucia Atehortùa2, Nathalie Giglioli-Guivarc’h1, Benoit St-Pierre1, Vincenzo De Luca3, Sarah E. O’Connor4 and Vincent Courdavault1* Abstract Background: Transcriptome sequencing offers a great resource for the study of non-model plants such as Catharanthus roseus, which produces valuable monoterpenoid indole alkaloids (MIAs) via a complex biosynthetic pathway whose characterization is still undergoing. Transcriptome databases dedicated to this plant were recently developed by several consortia to uncover new biosynthetic genes. However, the identification of missing steps in MIA biosynthesis based on these large datasets may be limited by the erroneous assembly of close transcripts and isoforms, even with the multiple available transcriptomes. Results: Secologanin synthases (SLS) are P450 enzymes that catalyze an unusual ring-opening reaction of loganin in the biosynthesis of the MIA precursor secologanin. We report here the identification and characterization in C. roseus of a new isoform of SLS, SLS2, sharing 97 % nucleotide sequence identity with the previously characterized SLS1. We also discovered that both isoforms further oxidize secologanin into secoxyloganin. SLS2 had however a different expression profile, being the major isoform in aerial organs that constitute the main site of MIA accumulation. Unfortunately, we were unable to find a current C.

  • Utility of a Phylogenetic Perspective in Structural Analysis of CYP72A Enzymes from Flowering Plants
    RESEARCH ARTICLE Utility of a Phylogenetic Perspective in Structural Analysis of CYP72A Enzymes from Flowering Plants Wil Prall, Oliver Hendy, Leeann E. Thornton* Department of Biology, The College of New Jersey, Ewing, New Jersey, United States of America * [email protected] a11111 Abstract Plant adaptation to external pressures depends on functional diversity in cytochrome P450 (CYP) enzymes. CYPs contain structural domains necessary for the characteristic P450 fold that allows monooxygenation, but they also have great variation in substrate binding affinity.

  • Folivory Elicits a Strong Defense Reaction in Catharanthus Roseus
    www.nature.com/scientificreports OPEN Folivory elicits a strong defense reaction in Catharanthus roseus: metabolomic and transcriptomic Received: 20 July 2016 Accepted: 06 December 2016 analyses reveal distinct local and Published: 17 January 2017 systemic responses Thomas Dugé de Bernonville1,*, Inês Carqueijeiro1,*, Arnaud Lanoue1, Florent Lafontaine1, Paloma Sánchez Bel2, Franziska Liesecke1, Karine Musset3, Audrey Oudin1, Gaëlle Glévarec1, Olivier Pichon1, Sébastien Besseau1, Marc Clastre1, Benoit St-Pierre1, Victor Flors2, Stéphane Maury4, Elisabeth Huguet3, Sarah E. O’Connor5 & Vincent Courdavault1 Plants deploy distinct secondary metabolisms to cope with environment pressure and to face bio- aggressors notably through the production of biologically active alkaloids. This metabolism-type is particularly elaborated in Catharanthus roseus that synthesizes more than a hundred different monoterpene indole alkaloids (MIAs). While the characterization of their biosynthetic pathway now reaches completion, still little is known about the role of MIAs during biotic attacks. As a consequence, we developed a new plant/herbivore interaction system by challenging C. roseus leaves with Manduca sexta larvae. Transcriptomic and metabolic analyses demonstrated that C. roseus respond to folivory by both local and systemic processes relying on the activation of specific gene sets and biosynthesis of distinct MIAs following jasmonate production. While a huge local accumulation of strictosidine was monitored in attacked leaves that could repel caterpillars through its protein reticulation properties, newly developed leaves displayed an increased biosynthesis of the toxic strictosidine-derived MIAs, vindoline and catharanthine, produced by up-regulation of MIA biosynthetic genes. In this context, leaf consumption resulted in a rapid death of caterpillars that could be linked to the MIA dimerization observed in intestinal tracts.
