  1. 1. Properties of Protein and Polymer Systems

    Författare :Fredrik Carlsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; lysozyme; mica; surface; dimerization; precipitation; aggregate; cluster; complex; polyelectrolyte; protein; polymer;

    Sammanfattning : Interactions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these systems.

  2. 2. On the role of actin in yeast protein quality control

    Författare :Lisa Larsson Berglund; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Protein quality control; Actin; Protein aggregate; Segregation; Polarisome; CCT; Huntingtin;

    Sammanfattning : Every cell is equipped with a protein quality control system to ensure the proper function of proteins. This is essential for both cell maintenance and the generation of new and healthy cells. LÄS MER

  3. 3. Fluorescent Probes and Protein Misfolding: Methods and Applications

    Författare :Irem Nasir; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; fluorophores; filter-trap; site-specific fluorophore labeling; amyloid-beta; microscopic rate constants; solvatochromic probes; alpha-synuclein; lipid vesicles; nanoparticles; protein adsorption;

    Sammanfattning : Protein misfolding is a frequently occurring event in living cells and without the quality control, the consequences are disasterous. In this thesis, we studied protein misfolding in vitro by employing a variety of fluorophores, to either detect the highly ordered aggregates of intrinsically disordered proteins/peptides or slight misfolding of a natively folded protein.

  4. 4. Stress response regulation and protein aggregate inheritance in Caulobacter crescentus

    Författare :Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; stress; protein aggregation; cellular aging; molecular chaperones; heat shock response; DnaK; sigma factor; suppressor genes; DNA replication; starvation; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many stress conditions a cell encounters threaten the continuation of basic biological processes ultimately endangering its survival. Heat shock and antibiotic exposure can lead to a sudden surge of protein un- and misfolding, while nutrient starvation directly causes a lack of energy and molecular building blocks. LÄS MER

  5. 5. On the interaction between wort protein and iso-humulone : A study of surface rheology, interfacial structures and particle formation with the relevance to beer foam

    Författare :Yi Lu; Institutionen för livsmedelsteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wort barley protein; lipid transfer protein; protein Z; iso-humulone; Ellipsometry; Surface rheology;

    Sammanfattning : Beer is one of the most popular drinks in the world. Foam is a unique characteristic of beer, contributing to mouthfeelings and visual perceptions. Therefore, it would be worthwhile to study the solution and interfacial properties ofbeer and assess them with regards to foam. LÄS MER
