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

    Author : Andreas Larsson; Jan Kihlberg; Fredrik Almqvist; Mats Larhed; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. 7. Perplexing Protein Puzzles

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

    Abstract : 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. READ MORE

  5. 8. Quantum Chemical Interpretation of Protein Crystal Structure

    Author : Kristina Nilsson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structure; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi; protein; ComQum-X; Hess2FF; QM MM; hetero-compound; metal; oxidation state; protonation; force field; quantum refinement; refinement;

    Abstract : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. READ MORE

  6. 9. Ensemble methods for protein structure prediction

    Author : Marcin J. Skwark; Arne Elofsson; Michael Tress; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; model quality assessment; contact prediction; homology modeling; ab-initio prediction; consensus prediction; structural bioinformatics; bioinformatics; protein structure; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Abstract : Proteins play an essential role in virtually all of life's processes. Their function is tightly coupled to the three-dimensional structure they adopt.Solving protein structures experimentally is a complicated, time- and resource-consuming endeavor. READ MORE

  7. 10. From Sequence to Structure : Using predicted residue contacts to facilitate template-free protein structure prediction

    Author : Mirco Michel; Arne Elofsson; Erik Lindahl; Johannes Söding; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein bioinformatics; protein structure prediction; contact prediction; machine learning; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Abstract : Despite the fundamental role of experimental protein structure determination, computational methods are of essential importance to bridge the ever growing gap between available protein sequence and structure data. Common structure prediction methods rely on experimental data, which is not available for about half of the known protein families. READ MORE
