  1. 11. Protein trafficking in the cell envelope of Escherichia coli : Identification and characterisation of a novel chaperone

    Författare :Hansjörg Götzke; Daniel Daley; Hans-Georg Koch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Sammanfattning : The cell envelope of Gram-negative bacteria, like Escherichia coli, is composed of a cytoplasmic membrane, a periplasmic space containing a peptidoglycan layer and an outer membrane. About 30 % of all proteins are localised in the cell envelope. LÄS MER

  3. 12. Shining light on unknown function proteins

    Författare :Riccardo Diamanti; Martin Högbom; Hans-Petter Hersleth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; metalloproteins; biochemistry; metabolism; biokemi; Biochemistry;

    Sammanfattning : The study of protein structure and function is a fundamental step for understanding biological systems and for creating a solid ground for future drug development. Despite the development of novel ground-breaking biochemical and bioinformatical tools in the last decades, most proteins found in nature still have unknown assigned function. LÄS MER

  4. 13. Photosystem II : organization, function and regulation

    Författare :Said Eshaghi; Matthias Rögner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : What makes plants, green algae and cyanobacteria so remarkable is their ability to convert light energy to chemical energy and at the same time evolve oxygen. In order to do so, they have developed a complex molecular machinery involving pigment and co-factor binding multi-protein complexes. LÄS MER

  5. 14. Modulators of Saccharomyces cerevisiae cytochrome c oxidase : Implications for the regulation of mitochondrial respiration

    Författare :Camilla Rydström Lundin; Peter Brzezinski; Christoph von Ballmoos; Shelagh Ferguson-Miller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; cytochrome c; OXPHOS; membrane protein; kinetics; ligand-binding; electron transfer; Rcf1; respiratory supercomplexes; Saccharomyces cerevisiae; Biochemistry; biokemi;

    Sammanfattning : Oxidative phosphorylation in mitochondria is performed by enzyme complexes and electron carriers that reside in the inner membrane. It is now generally accepted that these respiratory enzyme complexes assemble into larger so-called supercomplexes. However, it is presently not known why, under which conditions or how these supercomplexes form. LÄS MER

  7. 15. Mechanistic Insights in the Biogenesis and Function of the Respiratory Chain

    Författare :Hannah Dawitz; Martin Ott; Cristina Ugalde; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; respiratory chain; bc1 complex; cytochrome c oxidase; Cbp3; Rcf1; Rcf2; respiratory supercomplexes; biogenesis; mitochondria; Saccharomyces cerevisiae; Biochemistry; biokemi;

    Sammanfattning : Mitochondria fulfill a plethora of functions, including harboring metabolic pathways and converting energy stored in metabolites into ATP, the common energy source of the cell. This last function is performed by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. LÄS MER
