  1. 21. Computational Analysis of Molecular Recognition Involving the Ribosome and a Voltage Gated K+ Channel

    Författare :Martin Andér; Johan Åqvist; Lennart Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; molecular dynamics; ligand binding; binding free energy; linear interaction energy; codon recognition; translation termination; release factor; voltage gated potassium ion channel; Kv1.5; Structural biology; Strukturbiologi; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Over the last few decades, computer simulation techniques have been established as an essential tool for understanding biochemical processes. This thesis deals mainly with the application of free energy calculations to ribosomal complexes and a cardiac ion channel. LÄS MER

  3. 22. A Quantum Chemical View of Molecular and Nano-Electronics

    Författare :Jun Jiang; Yi Luo; Jim Greer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Sammanfattning : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.

  4. 23. Theoretical Description of the Electron-Lattice Interaction in Molecular and Magnetic Crystals

    Författare :Elham Mozafari; Igor A. Abrikosov; Sven Stafström; George Malcolm Stocks; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular crystals; Charge transport; Polaron; Magnetic materials; Paramagnetic state; Molecular dynamics;

    Sammanfattning : Electron-lattice interactions are often considered not to play a major role in material's properties as they are assumed to be small, the second-order effects. However, this study shows the importance of taking these effects into account in the simulations. LÄS MER

  5. 24. Folding and interaction studies of subunits in protein complexes

    Författare :Ximena Aguilar; Stefan Björklund; Alexis Verger; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macromolecular crowding; cpn10; Mediator; Med25; Dreb2a; VP16; conformational changes; NMR; ITC.; biokemi; Biochemistry; molekylärbiologi; Molecular Biology;

    Sammanfattning : Proteins function as worker molecules in the cell and their natural environment is crowded. How they fold in a cell-like environment and how they recognize their interacting partners in such conditions, are questions that underlie the work of this thesis. LÄS MER

  7. 25. Functional mapping and in vivo metabolism of the monoclonal antibody TS1 and its single-chain fragment : Its interaction with the antigen and the anti-idiotype

    Författare :Patrik Holm; Birgitta Sundström; Lars Gedda; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single-chain antibody; functional mapping; site-directed mutagenesis; immune complex; metabolism; Molecular biology; Molekylärbiologi; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : Antibodies are proteins capable of specific interactions to a wide range of molecules. These interactions are facilitated by the complementary determining regions (CDR).Carcinomas are the most common of human cancers and they release significant amount of cytokeratins (CK) in the necrotic areas of the tumors.
