  2. 6. The Role of Sugars for Protein Stabilization

    Author : Christoffer Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein; water; QENS; biomolecule; EPSR; amorphous; trehalose; neutron scattering; cryopreservation; DSC; neutron diffraction; dielectric spectroscopy;

    Abstract : The understanding of biomolecular interactions with water and co-solutes can lead to greater knowledge regarding the mechanisms behind biomolecular stabilization. This is highly important for developing technologies aimed to preserve biological materials. READ MORE

  4. 7. Structural Details of Human Aquaporin Regulation : Three stories of three aquaporins

    Author : Veronika Nesverova; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquaporin; membrane proteins; protein trafficking; water channel; aquaporin 0; aquaporin 5; aquaporin 2; cryo-EM; protein phosphorylation; protein-protein interaction; aquaporin regulation; aquaporins;

    Abstract : Every cell is surrounded by a thin plasma membrane, protecting it from its surrounding. Specialized protein channels and transporters are embedded in this membrane, ensuring selective transport of molecules in and out of the cells. To maintain optimal hydration, water channels called aquaporins (AQPs) are present in every cell of our body. READ MORE

  5. 8. Structural Transitions in Helical Peptides : The Influence of Water – Implications for Molecular Recognition and Protein Folding

    Author : Martin Lignell; Hans-Christian Becker; Kaare Teilum; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; protein folding; molten globule; time-resolved fluorescence spectroscopy; CD spectroscopy; molecular recognition; structure-function paradigm; Chemical physics; Kemisk fysik; Physical Chemistry; Fysikalisk kemi;

    Abstract : Fluctuations in protein structure are vital to function. This contrasts the dominating structure-function paradigm, which connects the well-defined three-dimensional protein structure to its function. However, catalysis is observed in disordered enzymes, which lack a defined structure. READ MORE

  6. 9. Interaction of trehalose with water and protein for the understanding of biological stabilization

    Author : Christoffer Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; trehalose; protein; neutron scattering; water; neutron diffraction; amorphous; cryopreservation; biomolecule; EPSR; DSC;

    Abstract : The understanding of biomolecular interactions with water and co-solutes opens up further understanding for the mechanism behind biomolecular stabilization. This is highly important for developing technologies aimed to preserve biological material. Such techniques include cryopreservation of for example pharmaceuticals or human organ transplants.

  7. 10. Molecular Association Studied by NMR Spectroscopy

    Author : Lars Nordstierna; István Furó; Peter Griffiths; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; spin relaxation; self-diffusion; intermolecular cross-relaxation; chemical shift; fluorinated surfactants; hydrogenated surfactant; micelle; non-ideal mixing; adsorption; hydration; surfactant-protein association; Physical chemistry; Fysikalisk kemi;

    Abstract : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. READ MORE
