1. 16. Ammonia assimilation and nitrogen fixation in phototrophic bacteria : studies on glutamine synthease and the metabolic regulation of nitrogenase in Rhodospirillum rubrum

   Författare :Abdelhamid Soliman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The phototrophic bacteria and a few other species, are able to control nitrogen fixation on the metabolic level. This is a fast and reversible mechanism, which “switches off and on” the nitrogenase activity in response to the accessibility of combined nitrogen, the energy supply and the level of oxygen in the medium.

7. 20. 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
