  1. 6. Capturing transient peptide assemblies associated with Alzheimer's disease : Native mass spectrometry studies of amyloid-β oligomerization

    Författare :Nicklas Österlund; Astrid Gräslund; Leopold L. Ilag; Mikael Oliveberg; Sheena E. Radford; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein aggregation; amyloid-β; neurodegeneration; Alzheimer’s disease; chaperones; DnaJ; biomembranes; native mass spectrometry; Biophysics; biofysik;

    Sammanfattning : Correct folding of proteins is essential for maintaining a functional living cell. Misfolding and aggregation of proteins, where non-native intermolecular interactions form large and highly ordered amyloid aggregates with low free energy, is hence associated with multiple diseases.

  2. 7. Accelerating the discovery of drugs for Neglected Tropical Diseases using biophysical methods

    Författare :Giulia Opassi; Helena Danielson; Jenny Sandmark; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neglected Tropical Diseases; Drug Discovery; Biochemistry; Biophysics; Kinetic; Fragment Based Lead Discovery; Assay Development;

    Sammanfattning : Even though they account for 10% of the global disease burden and besides the new record of funding in 2018, tropical diseases are still neglected by the majority of pharmaceutical companies and public funding. The reason can be mostly found in the fact that for these diseases a conventional drug discovery process is often too expensive. LÄS MER

  3. 8. Structural studies of drug targets and a drug metabolizing enzyme

    Författare :Daniela Cederfelt; U. Helena Danielson; Doreen Dobritzsch; Inari Kursula; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biophysics; Protein structure; X-ray crystallography; Cryogenic electron microscopy; Enzymology; Drug discovery; Pyrimidine degradation; Biokemi; Biochemistry;

    Sammanfattning : The work presented in this thesis describes how structural information about a protein can be acquired, and how it can be used to answer scientific questions about proteins’ function, their dynamic behaviour and their interactions with other proteins or ligands.The catalytic function of the pyrimidine-degrading, drug metabolizing enzyme β-ureidopropionase (βUP) is dependent on the shift between oligomeric states.

  5. 10. Structural investigation of human mitochondrial translation and off-target antibiotic binding

    Författare :Vivek Singh; Alexey Amunts; Yaser Hashem; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial translation; mitoribosome; electron cryo-microscopy; LRPPRC-SLIRP; antibiotics; streptomycin; Biophysics; biofysik;

    Sammanfattning : Human mitochondrial translation machinery has evolved to translate 13 mitochondrial mRNAs encoding components of the oxidative phosphorylation pathway responsible for ATP production. The structural basis of human mitochondrial translation is distinct from the canonical bacterial and cytosolic translation systems. LÄS MER
