  2. 1. Nucleotide-binding Proteins in the Plant Thylakoid Membrane

    Author : Sophie Heurtel Thuswaldner; Cornelia Spetea Wiklund; Bengt Persson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plant; Arabidopsis; photosynthesis; thylakoid membrane; nucleotide-binding; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Life on Earth is dependent on the oxygen produced through photosynthesis. The thylakoid membrane is the site for the light-driven reactions of photosynthesis, which oxidize water and supply energy in the form of ATP, mainly for carbon fixation. The utilization of ATP in the lumenal space of the thylakoid has not been considered in the past. READ MORE

  4. 2. NMR structral studies on ruthenium complexes binding to DNA

    Author : Lisha Wu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; DNA binding; Ru-complex dimer; CD; fluorescence; molecular dynamics simulation;

    Abstract : The Ru-complex Λ,Λ-[bidppz(bipy)4Ru2]4+ (Λ,Λ-B) exhibits multiple modes of interactions with the palindromic DNA dodecamer [d(CGCGAATTCGCG)]2, however excluding any type of intercalation as shown by both optical spectroscopy and NMR. NMR observation of Λ,Λ-B titration into a DNA solution results in both a transient binding, with observation of fast exchange for protons located near the ends of the DNA duplex, and a more stable interaction in the DNA minor groove indicated by a slow exchange mechanism and binding sites for G2, G4 and A5 of the same DNA strand.

  5. 3. How transient interactions in the crowded cytosol affect protein mobility and stability

    Author : Sarah Leeb; Mikael Oliveberg; Magnus Wolf-Watz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusive transient interactions; macromolecular crowding; protein stability; in-cell NMR; protein evolution; Biophysics; biofysik;

    Abstract : Most biochemical reactions have evolved in crowded intracellular environments. However, the complexity of intracellular environments is often neglected in structural or functional studies of proteins. READ MORE

  6. 4. Shining Light on Molecules : Electron Transfer Processes in Model Systems for Solar Energy Conversion Investigated by Transient Absorption Spectroscopy

    Author : Jens Föhlinger; Leif Hammarström; Davidsson Jan; Benjamin Dietzek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photophysics; photoinduced electron transfer; transient absorption spectroscopy; laser spectroscopy; solar energy conversion; p-type DSSCs; Charge separation; recombination; mesoporous NiO;

    Abstract : In the recent years, solar energy conversion has attracted a huge research interest due to the potential application for limiting the greenhouse effect. In many solar cells and solar fuel cells, understanding of charge transfer (CT) and recombination is important for future improvement of the overall efficiency. READ MORE

  7. 5. Molecular Metamorphosis in Transcriptional Regulation

    Author : Malin Lüking; Johan Elf; Victor Muñoz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein-DNA interactions; Facilitated diffusion; Binding Kinetics; Molecular Simulations; Fluorescence Microscopy; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : The foundation of all life is the interaction of molecules. Molecular interaction occurs in the tightly packed cytoplasm. In this crowded environment, the molecules need to be able to establish stable interactions with specific interaction partners, and with specific ones only. READ MORE
