  1. 1. Characterization of Mitilysin Pores by Cryo-electron Microscopy

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Vladimir Novakovic; [2023]
    Nyckelord :Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

    Sammanfattning : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. LÄS MER

  3. 2. Assessing the User Experienceof Hype Energy Drinks’ New Website : A study in UX development comparing the userexperience of two versions of the website Hype.com

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Vera Widmalm; [2023]
    Nyckelord :User Experience; UX; Web development; Online product marketing; Nutrition;

    Sammanfattning : This study explores the optimization of user experience (UX) and website goals through arelatively small-scale test with 10 participants. The research focuses on evaluating theimplementation of a new website prototype for Hype Energy Drinks, with an aim to improvehealth orientation and UX, specifically when communicating the product sections for isotonicdrinks and protein products.

  4. 3. Polarizability and Orientation Dynamics of Small Proteins

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Ebba Koerfer; [2022]
    Nyckelord :Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Sammanfattning : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. LÄS MER

  5. 4. The effect of water on the orientation of a protein in an electric field

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Gideon Elfrink; [2022]
    Nyckelord :Structure determination; Gromacs; tutorial; Molecular Dynamics; protein; ubiquitin;

    Sammanfattning : Structure determination of proteins is vital for the understanding of their function. It often relies on techniques that use intense X-ray pulses to create diffraction patterns of protein crystals, which then contain information on the three-dimensional structure of the crystallised protein.

  7. 5. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields

    Kandidat-uppsats, Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysik

    Författare :Adi Bijedic; [2021]
    Nyckelord :;

    Sammanfattning : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. LÄS MER
