  2. 6. Nanoscopic adventures : unraveling macromolecular complexes in infectious diseases via integrative structural biology

    Author : Kai Patric Ehrenbolger; Ronnie Berntsson; Felipe Cava; Jonas Barandun; David Drew; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infectious diseases; E. faecalis; Microsporidia; Ribosome; Proteasome; Polar Tube; Structural Biology; Single particle Cryo-Electron Microscopy;

    Abstract : This thesis focuses on understanding the underlying molecular mechanisms of infectious diseases, which claim nearly 9 million lives annually. The research centers on critical analysis of pathogen mechanisms and drug resistance. I have mainly focused on two clades of pathogens: Enterococcus faecalis and microsporidia. E. READ MORE

  4. 7. Targeting Infectious Disease : Structural and functional studies of proteins from two RNA viruses and Mycobacterium tuberculosis

  5. 8. Fighting Tuberculosis – : Structural Studies of Three Mycobacterial Proteins

    Author : Alina Castell; Torsten Unge; Manfred Weiss; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mycobacterium tuberculosis; Rv0216; Rv0130; Mycobacterium smegmatis; branched chain aminotransferase; X-ray crystallography; fatty acid metabolism; Structural biology; Strukturbiologi;

    Abstract : This thesis presents the cloning, purification, crystallization, and structural studies of two unknown proteins from Mycobacterium tuberculosis, and of an aminotransferase from Mycobacterium smegmatis. Structural knowledge of these proteins is of highest interest for structure-based drug design, which is one of the approaches that can be used in order to fight tuberculosis (TB). READ MORE

  6. 9. Structural and functional properties of transthyretin

    Author : Anders Karlsson; A. Elisabeth Sauer-Eriksson; Salam Al-Karadaghi; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Amyloidosis; X-ray crystallography; Protein structure; Protein; Structural biology; Strukturbiologi;

    Abstract : The hereditary transthyretin (TTR) amyloidoses are rare, and in severe cases, fatal disorders caused by mutations in the TTR gene. The clinical picture is diverse, involving neuropathies and myopathies, and mainly depends on the causative mutation and the sites and rates of amyloid deposition. READ MORE

  7. 10. Of spiders, bugs, and men : Structural and functional studies of proteins involved in assembly

    Author : Wangshu Jiang; Stefan D Knight; Steve J. Matthews; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein assembly; sulfate transporter; crystallography; Proteus mirabilis; fimbriae; adhesin; urinary tract infection; biofilm; spider silk; asymmetric dimer; Bri2; BRICHOS; molecular chaperone; Alzheimer s disease; amyloid; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : Protein assembly enables complex machineries while being economical with genetic information. However, protein assembly also constitutes a potential threat to the host, and needs to be carefully regulated.Sulfate is a common source of sulfur for cysteine synthesis in bacteria. READ MORE
