  1. 1. Structural basis for metalloprotein catalysis : Characterization of Mycobacterium tuberculosis phosphatidylinositol phosphate synthase PgsA1 and Bacillus anthracis ribonucleotide reductase R2

    Författare :Kristīne Grāve; Martin Högbom; Susanna Törnroth-Horsefield; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Sammanfattning : About a third of all proteins need to associate with a particular metal ion or metallo-inorganic cofactor to function. This interplay expands the catalytic repertoire of enzymes and reflects the adaption of these catalytic macromolecules to the environments they have evolved in. LÄS MER

  2. 2. Structural studies of the surface adhesin SspB from Streptococcus gordonii

    Författare :Nina Forsgren; Karina Persson; Inger Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus gordonii; X-ray crystallography; surface adhesin; dental plaque; structural biology; Structural biology; Strukturbiologi; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Surface proteins on microorganisms that build up the oral biofilm are key players in the formation of the biofilm. Antigen I/II proteins are surface adhesins found on virtually all oral streptococci and share a conserved multi-domain architecture. These adhesins bind surface components on other bacteria and on host cells. LÄS MER

  3. 3. Metal-Organic Frameworks (MOFs) for Heterogeneous Catalysis : Synthesis and Characterization

    Författare :Mikaela Gustafsson; Xiaodong Zou; Pascal Van Der Voort; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal-organic frameworks; zeolitic imidazolate frameworks; functionalized linkers; structural transformation; heterogeneous catalysis; Structural Chemistry; strukturkemi;

    Sammanfattning : Metal-organic frameworks (MOFs) are crystalline hybrid materials with interesting chemical and physical properties. This thesis is focused on the synthesis and characterization of different MOFs and their use in heterogeneous catalysis. LÄS MER

  4. 4. Transthyretin and the transthyretin-related protein: A structural study

    Författare :Erik Lundberg; A. Elisabeth Sauer-Eriksson; Lennart Sjölin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Transthyretin-related protein; X-ray crystallography; Protein structure; Amyloidosis; Structural biology; Strukturbiologi;

    Sammanfattning : Transthyretin (TTR) is one of several proteins involved in amyloid disease in humans. Unknown conformational changes of the native state of TTR result in aggregation of TTR molecules into amyloid fibrils, which accumulate in extracellular tissues. This may result in different clinical symptoms, e.g. LÄS MER
