  1. 1. Protein Engineering of Extracellular Superoxide Dismutase : Characterization of Binding to Heparin and Cellular Surfaces

    Författare :Ing-Marie Ahl; Lena Tibell; Bengt-Harald Jonsson; Steen Vang Petersen; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Accumulating evidence indicates that oxygen free radicals are involved in many diseases and pathological conditions, such as aging, inflammation, reperfusion damage of ischemic tissue and various cardiovascular diseases. Extracellular superoxide dismutase (ECSOD) thus plays a major role in the maintenance of cells by providing protection against these toxic substances in the extracellular space. LÄS MER

  3. 2. Improved Methods for Characterization of Protein Dynamics by NMR spectroscopy and Studies of the EphB2 Kinase Domain

    Författare :Alexandra Ahlner; Patrik Lundström; Bengt-Harald Jonsson; Lena Mäler; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Proteins are essential for all known forms of life and in many lethal diseases protein failure is the cause of the disease. To understand proteins and the processes they are involved in, it is valuable to know their structures as well as their dynamics and interactions. LÄS MER

  4. 3. The Folding Energy Landscape of MerP

    Författare :Ann-Christin Brorsson; Bengt-Harald Jonsson; Daniel Otzen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein folding and stability; hydrogen exchange; intermediate; partial unfolding; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : This thesis is based on studies, described in four papers, in which the folding energy landscape of MerP was investigated by various techniques. MerP is a water-soluble 72 amino acid protein with a secondary structure consisting of four anti-parallel β-strands and two α-helices on one side of the sheet in the order β1α1β2β3α2β4. LÄS MER

  5. 4. SOD1´s Law : An Investigation of ALS Provoking Properties in SOD1

    Författare :Roberth Byström; Gerhard Gröbner; Stefan Marklund; Mikael Oliveberg; Bengt-Harald Jonsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; amyotrophic lateral sclerosis; SOD1; protein folding; membrane interaction; aggregates; survival time; repulsive charge; Biochemistry; Biokemi;

    Sammanfattning : Proteins are the most important molecules in the cell since they take care of most of the biological functions which resemble life. To ensure that everything is working properly the cell has a rigorous control system to monitor the proper function of its proteins and sends old or dysfunctional proteins for degradation. LÄS MER

  7. 5. Understanding the dual nature of lysozyme: part villain – part hero : A Drosophila melanogaster model of lysozyme amyloidosis

    Författare :Linda Helmfors; Ann-Christin Brorsson; Bengt-Harald (Nalle) Jonsson; R. Luke Wiseman; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Amyloid proteins are a distinct class of proteins that can misfold into β-sheet rich structures that later mature to form the characteristic species known as amyloid fibrils, and accumulate in tissues in the human body. The misfolding event is often caused by mutations (or outer factors such as changes in pH) that destabilize the native protein structure. LÄS MER
