  1. 1. Structural and thermodynamical basis for molecular recognition between engineered binding proteins

    Författare :Jakob Dogan; Per-Åke Nygren; John E. Ladbury; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein structure; induced fit; binding thermodynamics; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; calorimetry; Structural biochemistry; Strukturbiokemi;

    Sammanfattning : The structural determination of interacting proteins, both as individual proteins and in their complex, complemented by thermodynamical studies are vital in order to gain in-depth insights of the phenomena leading to the highly selective protein-protein interactions characteristic of numerous life processes. This thesis describes an investigation of the structural and thermodynamical basis for molecular recognition in two different protein-protein complexes, formed between so-called affibody proteins and their respective targets.

  2. 2. Intra- and intermolecular interactions in proteins : Studies of marginally hydrophobic transmembrane alpha-helices and protein-protein interactions

    Författare :Linnea E Hedin; Arne Elofsson; Susana Cristobal; Ismael Mingarro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane proteins; membrane insertion; marginally hydrophobic helix; hydrophobicity; protein-protein interactions; LacY; GltPh; Cell and molecular biology; Cell- och molekylärbiologi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Most of the processes in a living cell are carried out by proteins. Depending on the needs of the cell, different proteins will interact and form the molecular machines demanded for the moment. LÄS MER

  3. 3. Antiadhesive agents targeting uropathogenic Escherichia coli : Multivariate studies of protein-protein and protein-carbohydrate interactions

    Författare :Andreas Larsson; Jan Kihlberg; Fredrik Almqvist; Mats Larhed; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Antibacterial; pili; antiadhesive agents; structure based design; statistical molecular design; 2-pyridone; amino acid derivative; galabiose; enaminone; SPR; ELISA; QSAR; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis describes studies directed towards development of novel antiadhesive agents, with particular emphasis on compounds that prevent attachment of bacteria to a host-cell. Three different proteins involved in the assembly or function of adhesive pili in uropathogenic Escherichia coli have been targeted either by rational structure based design or statistical molecular methods.

  4. 4. Carbon Nitride : Characterization and Protein Interactions

    Författare :Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. LÄS MER

  5. 5. 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.
