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

    Author : Christofer Lendel; Per-Åke Nygren; Christopher M. Dobson; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  3. 3. Protein folding without loops and charges

    Author : Martin Kurnik; Mikael Oliveberg; Kevin W. Plaxco; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; folding cooperativity; protein aggregation; protein charges; protein engineering; Biochemistry; biokemi;

    Abstract : Going down the folding funnel, proteins may sample a wide variety of conformations, some being outright detrimental to the organism. Yet, the vast majority of polypeptide molecules avoid such pitfalls. Not only do they reach the native minimum of the energy landscape; they do so via blazingly fast, biased, routes. READ MORE

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

    Author : Elisabet Wahlberg; Per-Åke Nygren; Bengt-Harald Jonsson; KTH; []
    Keywords : 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;

    Abstract : 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. Ribosomal Stalk Protein L12 : Structure, Function and Application

    Author : Chandra Sekhar Mandava; Suparna Sanyal; Knud Nierhaus; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome; protein synthesis; L12 dimer; initiation; elongation; G factors; and His-tag; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Ribosomal stalk proteins are known to play important role in protein synthesis. The ‘stalk’, an extended structure on the large subunit of the ribosome is composed mainly of two to three dimers of L12 and one L10 protein, which forms the base of the stalk. In E. READ MORE
