  1. 11. Protein stabilization. Some methods and mechanisms

    Författare :Maria Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER

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

    Författare :Karin Julenius; Biofysikalisk kemi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 13. Thermodynamics of protein-DNA interactions

    Författare :Thomas Lundbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DNA-protein interactions; molecular recognition; thermodynamics; specificity.dehydration; salt dependence.;

    Sammanfattning : This thesis treats the molecular recognition between DNA-binding proteins and DNA and the way these interactions are affected by the surrounding water solution and dissolved solutes. The work involves studies on the thermodynamics of sequence specific DNA-binding of the human glucocorticoid receptor DNA-binding domain and the nonsequence specific DNA- binding of Sso7d from the archaeon Sulfolobus solfataricus.

  4. 14. Functionality of Spray-Dried Whey Protein Powders - Surface Composition, Particle Morphology and Rehydration

    Författare :Ida-Marie Andersson; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality;

    Sammanfattning : Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. LÄS MER

  5. 15. Exploring the functionality of coconut proteins

    Författare :Borges Chambale; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

    Sammanfattning : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry. LÄS MER
