  1. 1. Molecular principles of protein stability and protein-protein interactions

    Författare :Christofer Lendel; Per-Åke Nygren; Christopher M. Dobson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; binding thermodynamics; induced fit; molten globule; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; protein structure.; Structural biochemistry; Strukturbiokemi;

    Sammanfattning : Proteins with highly specific binding properties constitute the basis for many important applications in biotechnology and medicine. Immunoglobulins have so far been the obvious choice but recent advances in protein engineering have provided several novel constructs that indeed challenge antibodies. LÄS MER

  2. 2. Perplexing Protein Puzzles

    Författare :Stina Lindman; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; calbindin D9k; split-GFP; protein G B1; pKa-values; protein reconstitution; Electrostatic interactions; protein stability; protein denaturation; heteronuclear NMR; pH titrations;

    Sammanfattning : Protein structure and stability are inherent in the amino acid sequence and governed by non-covalent interactions. The cooperation between forces is, however, perplexing and not well understood. In order to elucidate and predict protein folding and stability, detailed studies of non-covalent interactions are required. LÄS MER

  3. 3. Unravelling protein stability and aggregation

    Författare :Tanja Weiffert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

    Sammanfattning : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. LÄS MER

  4. 4. Structure determination and thermodynamic stabilization of an engineered protein-protein complex

    Författare :Elisabet Wahlberg; Per-Åke Nygren; Bengt-Harald Jonsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; protein structure; coupled folding; NMR spectroscopy; protein stability; protein-protein interactions; binding thermodynamics; isothermal titration calorimetry; protein engineering; Structural biochemistry; Strukturbiokemi;

    Sammanfattning : The interaction between two 6 kDa proteins has been investigated. The studied complex of micromolar affinity (Kd) consists of the Z domain derived from staphylococcal protein A and the related protein ZSPA-1, belonging to a group of binding proteins denoted affibody molecules generated via combinatorial engineering of the Z domain.

  5. 5. The Interaction Between the Chaperonin GroEL and Human Carbonic Anhydrase II : Protein Folding and Stability Studies

    Författare :Malin Persson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonic anhydrase; protein folding; protein stability; chaperone; GroEL; folding mechanism; site-directed spinlabeling; electron paramagnetic resonance EPR ;

    Sammanfattning : The presence of GroEL/ES during the refolding of human carbonic anhydrase II was found to increase the yield of active enzyme from approx. 70 to approx. 100%. This chaperone action on the enzyme could be obtained by adding GroEL alone, and the time course in that case was only moderately slower than the spontaneous process. LÄS MER
