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

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

   Abstract : 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. READ MORE

4. 2. Structural Studies of Glutamine Synthetases – Towards the Development of Novel Antitubercular Agents

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

   Abstract : 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. READ MORE

7. 5. Structural studies of small viruses using an X-ray Free Electron Laser

   Author : Anna Munke; Marvin Seibert; Dirk Hasse; Inger Andersson; Carl Caleman; Maria Selmer; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Abstract : X-ray crystallography has since its introduction been the most successful technique for solving protein structures. Viruses however, often possess structural components such as fibrils, tails and envelopes that make them difficult or impossible to crystallize. READ MORE
