  • 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.

Efficient heterocyclisation by (di)terpene synthases Abstract While cyclic ether forming terpene synthases are known, the basis for such heterocyclisation is unclear. Here it is reported that numerous (di)terpene synthases, particularly including the ancestral ent-kaurene synthase, efficiently oducepr isomers of manoyl oxide from the stereochemically appropriate substrate. Accordingly, such heterocyclisation is easily accomplished by terpene synthases. Indeed, the use of single residue changes to induce production of the appropriate substrate in the upstream active site leads to efficient bifunctional enzymes oducingpr isomers of manoyl oxide, representing novel enzymatic activity.

  • Genomic Organization of Plant Terpene Synthases and Molecular Evolutionary Implications
    Copyright 2001 by the Genetics Society of America Genomic Organization of Plant Terpene Synthases and Molecular Evolutionary Implications Susan C. Trapp and Rodney B. Croteau Institute of Biological Chemistry, Washington State University, Pullman, Washington 99164-6340 Manuscript received November 30, 2000 Accepted for publication March 1, 2001 ABSTRACT Terpenoids are the largest, most diverse class of plant natural products and they play numerous functional roles in primary metabolism and in ecological interactions. The ®rst committed step in the formation of the various terpenoid classes is the transformation of the prenyl diphosphate precursors, geranyl diphosphate, farnesyl diphosphate, and geranylgeranyl diphosphate, to the parent structures of each type catalyzed by the respective monoterpene (C10), sesquiterpene (C15), and diterpene synthases (C20). Over 30 cDNAs encoding plant terpenoid synthases involved in primary and secondary metabolism have been cloned and characterized. Here we describe the isolation and analysis of six genomic clones encoding terpene synthases of conifers, [(Ϫ)-pinene (C10), (Ϫ)-limonene (C10), (E)-␣-bisabolene (C15), ␦-selinene (C15), and abietadiene synthase (C20) from Abies grandis and taxadiene synthase (C20) from Taxus brevifolia], all of which are involved in natural products biosynthesis. Genome organization (intron number, size, placement and phase, and exon size) of these gymnosperm terpene synthases was compared to eight previously character- ized angiosperm terpene synthase genes and to six putative terpene synthase genomic sequences from Arabidopsis thaliana. Three distinct classes of terpene synthase genes were discerned, from which assumed patterns of sequential intron loss and the loss of an unusual internal sequence element suggest that the ancestral terpenoid synthase gene resembled a contemporary conifer diterpene synthase gene in containing at least 12 introns and 13 exons of conserved size.
