  1. 16. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems

    Author : Tobias Nilsson; Peter Brzezinski; Petra Hellwig; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; Biochemistry; biokemi;

    Abstract : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. READ MORE

  2. 17. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k

    Author : Karin Julenius; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface plasmon resonance; fluorescence spectroscopy; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Abstract : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. READ MORE

  3. 18. Polymer and Protein Physics : Simulations of Interactions and Dynamics

    Author : Anna Sinelnikova; Johan Nilsson; Carl Caleman; Erik Lindahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; proteins; Monte Carlo; molecular dynamics; phase diagram; renormalisation group; SPI; polymer effective model; coarse-graining; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. READ MORE

  4. 19. Effects of Macromolecular Crowding on Protein Folding : - in-vitro equilibrium and kinetic studies on selected model systems

    Author : Alexander Christiansen; Pernilla Wittung-Stafshede; Thomas Kiefhaber; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein Folding; macromolecular crowding; excluded volume; spectroscopy; stopped-flow; biokemi; Biochemistry;

    Abstract : Protein folding is the process during which an extended and unstructured polypeptide converts to its compact folded structure that is most often the functional state. The process has been characterized extensively in dilute buffer in-vitro during the last decades but the actual biological place for this process is the inside of living cells. READ MORE

  5. 20. Protein folding, stability and recognition

    Author : Jianxin Duan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Protein; folding; stability; recognition; molecular dynamics; protein-DNA interactions; simulation;

    Abstract : Proteins make up for most of the dry mass of a cell and they are highly involved in virtually all cellular processes. The importance of the proteins is reflected by frequent association between dysfunctional proteins and diseases. Proteins have also wide applications in industries. READ MORE
