1. 11. Protein complexes : assembly, structure and function

   Författare :Kristina Wilhelm; Ludmilla Ludmilla Morozova-Roche; Catharina Svanborg; Umeå universitet; []
   Nyckelord :HAMLET; ELOA; lysozyme; amyloid; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning :  Most proteins must fold into their native conformations to fulfil their biological functions. Failure of proteins to fold leads to cell pathology and a broad range of human diseases referred to as protein misfolding disease, e.g., Alzheimer’s disease, Parkinson’s disease, and type II diabetes.

3. 12. Recombinant subunit vaccines : protein immunogens

   Författare :Sissela Liljeqvist; KTH; []
   Nyckelord :;

   Sammanfattning : Recombinant techniques provide valuable tools for thedevelopment of modern subunit vaccines. In this thesisdifferent systems for production of recombinant subunitvaccines are presented. The strategies investigated includeprotein immunogens, live bacterial vectors and nucleicacids. LÄS MER

4. 13. The birth and growth of the protein folding nucleus : Studies of protein folding focused on critical contacts, topology and ionic interactions

   Författare :Linda Hedberg; Mikael Oliveberg; Christopher Johnson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; chevron plot; transition-state movements; Hammond behaviour; topology; electrostatic interactions; pH dependence; mass-action; protein engineering; pKa; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Proteins are among the most complex molecules in the cell and they play a major role in life itself. The complexity is not restricted to just structure and function, but also embraces the protein folding reaction. LÄS MER

5. 14. Exploring small heat shock protein chaperones by crosslinking mass spectrometry

   Författare :Wietske Lambert; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cross-linking; mass spectrometry; protein-protein interactions; Hsp21; BS3; DTSSP; MALDI-TOF TOF; client protein; substrate; aggregation; unfolded protein; chaperone; Small heat shock protein; crosslinking;

   Sammanfattning : Together with other molecular chaperones, small heat shock proteins are key components of the protein quality control system, which is comprised of several hundred proteins and acts to maintain proteome homeostasis in the cell. Small heat shock proteins bind unfolding proteins at an early stage, to prevent these from further unfolding and aggregating. LÄS MER

7. 15. Water and protein solutions studied by field-dependent magnetic relaxation

   Författare :Kristofer Modig; Biofysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxation; protein solvation; protein dynamics; protein denaturation; oxytocin; magnetic relaxation dispersion; nuclear magnetic resonance; lipid-binding protein; hydration; beta-lactoglobulin; BPTI; shielding anisotropy; water; Molecular biophysics; Molekylär biofysik;

   Sammanfattning : In the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. LÄS MER
