    Sammanfattning : Tuberculosis, caused by the pathogenic bacteria Mycobacterium tuberculosis, is one of the most widespread and deadly infectious diseases today. Treatment of tuberculosis relies on antibiotics that were developed more than 50 years ago. These are now becoming ineffective due to the emergence of antibiotic resistant strains of the bacteria.

  4. 3. Fighting Tuberculosis – : Structural Studies of Three Mycobacterial Proteins

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

    Sammanfattning : 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). LÄS MER

  5. 4. Structural and Functional Studies of Peptidyl-prolyl cis-trans isomerase A and 1-deoxy-D-xylulose- 5-phosphate reductoisomerase from Mycobacterium tuberculosis

    Författare :Lena M Henriksson; Torsten Unge; Sherry L. Mowbray; Barbara Seaton; Uppsala universitet; []
    Nyckelord :Molecular biology; Mycobacterium tuberculosis; Rv0009; peptidyl-prolyl cis-trans isomerase; Rv2870c; 1-deoxy-D-xylulose-5-phosphate reductoisomerase; non-mevalonate pathway; DOXP MEP pathway; X-ray crystallography; Molekylärbiologi;

    Sammanfattning : Mycobacterium tuberculosis, the causative pathogen of tuberculosis, currently infects one-third of the world’s population, resulting in two million deaths annually. This clearly shows that tuberculosis is one of the most serious diseases of our times. LÄS MER

  7. 5. Structural Studies of Glutamine Synthetases – Towards the Development of Novel Antitubercular Agents

    Författare :Wojciech W. Krajewski; Sherry L. Mowbray; Torsten Unge; Thomas C. Terwilliger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural biology; Strukturbiologi;

    Sammanfattning : Glutamine synthetase (GS) plays an important role in nitrogen metabolism, where it catalyzes the ATP-dependent condensation of glutamate and ammonia to yield glutamine. Recent studies showed the importance of M. tuberculosis GS (MtGS) for growth and survival of the bacterium, and demonstrated its potential as a drug target. LÄS MER
