    Sammanfattning : The aim of this Thesis was to improve our understanding and assessment of feeding conditions for zooplanktivorous fish in the Baltic Sea.We investigated (papers I, II) the usefulness of biochemical proxies for assessments of growth and metabolic rates in the dominant Baltic copepod Acartia bifilosa.

  3. 2. Characterization of Amino Acid tRNA Ligases using the Analytical Ultracentrifuge

    Författare :Lars Lundvik; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amino acid tRNA ligase; analytical ultracentrifugation;

    Sammanfattning : ABSTRACT. Quaternary structures of amino acid tRNA ligases/synthetases (aaRS) in the native as well as in denatured forms were examined by molecular weight determinations (paper I-IV). Analytical ultracentrifugation, gel electrophoresis, gel chromatography were used in these investigations. LÄS MER

  4. 3. Design and Synthesis of Potential Aminoacyl-tRNA Synthetase Inhibitors

    Författare :Itedale Namro Redwan; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aminoacyl tRNA synthetases; Aminoacyl-AMP; Bioisosteres; Amino Acids; Solution-Phase; Protective Groups; Solid-Phase Chemistry; Molecular Modelling; Biological Evaluation;

    Sammanfattning : Aminoacyl-tRNA synthetases (aaRSs) are essential enzymes present in all living organisms, their catalytic activity is involved in the translation of the genetic code into functional proteins and they are potential targets for anti-infective agents. The first step in the biosynthetic pathway catalysed by aaRSs consists of activation of the corresponding amino acid by the reaction with ATP to form an aminoacyl-adenylate (aa-AMP), the key intermediate in the biosynthesis of proteins.
