  1. 1. Kinetic Recognition of Nucleic Acids - Studies on the DNA Binding Selectivity of Threading Ruthenium Complexes

    Författare :Pär Nordell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intercalation; circular dicroism; ruthenium complexes; sequence selectivity; fluorescence; DNA; supercoiling; spectroscopy; kinetics;

    Sammanfattning : Despite the great progress in our understanding of DNA during the past half-century, there are many important aspects of its chemical and biological role yet to be explored. The principles by which it selectively interacts with other molecules have attracted much interest due to the relevance for fundamental cellular processes, as well as for the development of diagnostic probes and effective pharmaceutical agents.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous Materials; Magnetism; Amorphous Magnetism; Magnetic Measurements; Thin Films; Multilayers; Thin Film Deposition; Sputtering; FeZr Alloys; AlZr Alloys; X-ray Diffraction; Rutherford Backscattering Spectrometry; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : The scope of this thesis is the study of the interplay between structure and magnetism in amorphous materials. The investigations focus on the growth of amorphous layers and the study of the influence of structural disorder and reduced physical extension on the magnetic properties of thin films and multilayers.

  4. 3. Regulation of photosynthesis -Cytochrome b6f in redox regulation -Two novel proteases acting on an N-terminal peptide of LHCII

    Författare :Jörgen Ström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; Växtbiokemi; cGEP; proteolysis; protease; protein phosphorylation; redox regulation; light-harvesting antenna; cytochrome b6f; chloroplast; Photosynthesis;

    Sammanfattning : In higher plants photosynthesis takes place in the chloroplast. This work focuses on two different processes that effects photosynthesis. Firstly, we studied the events occurring prior to the phosphorylation of LHCII. Secondly, we also studied two novel proteases, with the potential to degrade LHCII. LÄS MER
