  1. 16. Mutational effects on protein structure and function

    Författare :Jonas Carlsson; Persson Bengt; Uwe Sauer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mutation; prediction; phenotypes; homology model; virtual screening; molecular dynamics; amyloid; cancer; membrane protein; Bioinformatics; Bioinformatik;

    Sammanfattning : In this thesis several important proteins are investigated from a structural perspective. Some of the proteins are disease related while other have important but not completely characterised functions. LÄS MER

  3. 17. Causes of Substitution Frequency Variation in Pathogenic Bacteria

    Författare :Wagied Davids; Siv Andersson; Otto Berg; Bengt Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Comparative genomics; Molecular evolution; Bioinformatics; Human pathogens; Rickettsia; Helicobacter pylori; Biologi; Biology; Biologi;

    Sammanfattning : Estimating substitution frequencies at sites that influence (Ka) and do not influence (Ks) the amino acid sequence is important for understanding the dynamics of molecular sequence evolution and the selective pressures that have shaped genetic variation. The aim of this work was to gain a deeper understanding of the driving forces of substitution frequency variation in human pathogens. LÄS MER

  4. 18. Bioinformatic protein family characterisation

    Författare :Joel Hedlund; Bengt Persson; Jaap Heringa; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Biological research is necessary; not only to further our understanding of the processes of life, but also to combat disease, hunger and environmental damage.Bioinformatics is the science of handling biological information. It entails integrating, structuring and analysing the ever-increasing amounts of available biological data. LÄS MER

  5. 19. Nucleotide-binding Proteins in the Plant Thylakoid Membrane

    Författare :Sophie Heurtel Thuswaldner; Cornelia Spetea Wiklund; Bengt Persson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant; Arabidopsis; photosynthesis; thylakoid membrane; nucleotide-binding; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Life on Earth is dependent on the oxygen produced through photosynthesis. The thylakoid membrane is the site for the light-driven reactions of photosynthesis, which oxidize water and supply energy in the form of ATP, mainly for carbon fixation. The utilization of ATP in the lumenal space of the thylakoid has not been considered in the past. LÄS MER

  7. 20. Regulatory and Structural Properties of the High-Affinity Phosphate Acquisition System in Saccharomyces cerevisiae

    Författare :Jens Lagerstedt; Bengt L. Persson; Joseph W. DePierre; Peter J. Henderson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : Inorganic phosphate is an essential nutrient required for the synthesis of many cellular components (e.g., nucleic acids, proteins, lipids and sugars), as well as for meeting metabolic needs (e.g. LÄS MER
