  1. 1. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State

    Author : Anna Reymer; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; intercalation; homologous recombination; DNA; ruthenium II polypyridyl compounds; human Rad51;

    Abstract : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.

  2. 2. Alexandria: A General Drude Polarizable Force Field with Spherical Charge Density

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mohammad Mehdi Ghahremanpour; David Van der Spoel; Kresten Lindorff-Larsen; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular mechanics; Force field; Drude oscillator model; Alexandria library; GROMACS; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Molecular-mechanical (MM) force fields are mathematical functions that map the geometry of a molecule to its associated energy. MM force fields have been extensively used for an atomistic view into the dynamic and thermodynamics of large molecular systems in their condensed phase. READ MORE

  3. 3. Amyloid-β and lysozyme proteotoxicity in Drosophila Beneficial effects of lysozyme and serum amyloid P component in models of Alzheimer’s disease and lysozyme amyloidosis

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Liza Bergkvist; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In the work presented this thesis, two different conditions that are classified as protein misfolding diseases: Alzheimer's disease and lysozyme amyloidosis and proteins that could have a beneficial effect in these diseases, have been studied using Drosophila melanogaster, commonly known as the fruit fly. The fruit fly has been used for over 100 years to study and better understand fundamental biological processes. READ MORE

  4. 4. Thermodynamical and structural properties of proteins and their role in food allergy

    University dissertation from Umeå : Umeå universitet

    Author : Louise Rundqvist; Umeå universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Protein folding; NMR; Food allergy; allergen; protein interactions; medicinsk biokemi; Medical Biochemistry;

    Abstract : Proteins are important building blocks of all living organisms. They are composed of a defined sequence of different amino acids, and fold into a specific three-dimensional, ordered structure. The three-dimensional structure largely determines the function of the protein, but protein function always requires motion. READ MORE

  5. 5. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hemanth Kumar Narayana Reddy; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE
