  1. 1. On the Development of Mucin-based Biomaterial Coatings

    Author : Tomas Sandberg; Karin Caldwell; Jan Carlsson; Thomas Arnebrant; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucin; Biomaterial; Surface-exposed protein; XPS; Neutrophil; Cell morphology; SEM; QCM-D; Viscoelasticity; Protein-stabilization; HNL; Coating; MG1; BSM; PGM; SEC-MALS-RI; Mucin quantification; Protein adsorption; Ellipsometry; Biomaterials; Biomaterial;

    Abstract : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. READ MORE

  2. 2. Molecular characterization of protein phosphorylation in plant photosynthetic membranes

    Author : Maria Hansson; Alexander V. Vener; Jean-David Rochaix; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein phosphorylation; photosynthesis; mass spectrometry; protein characterization; Cell biology; Cellbiologi;

    Abstract : Higher plants cannot move to a more favorable place when the environmental conditions are changing. To adapt to changes in light, temperature and access to water the plants had to evolve special mechanisms at the molecular level. READ MORE

  3. 3. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Author : Malin Mejàre; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Abstract : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. READ MORE

  4. 4. Protein Surfaces Probed by Aqueous Two-phase Partitioning

    Author : Kristina Berggren; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; partitioning; Aqueous two-phase systems; protein surface; peptide; Biochemistry; amino acid residue; Biokemi;

    Abstract : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. READ MORE

  5. 5. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

    Author : Niklas Gustavsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

    Abstract : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. READ MORE
