  1. 21. Protonmotive coupling of energy conversion processes in photosyntetic bacteria : studies on membrane energization and photophosphorylation capacity

    Författare :Beston F. Nore; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fotosyntes;

    Sammanfattning : This work is a study on the membrane-bound inorganic pyrophosphatase and other energylinkedenzymes in the chromatophores from the photosynthetic bacterium Rhodospirillum rubrum.The membrane-bound inorganic pyrophosphatase is functionally similar to the well-known FiF0-ATP synthase.

  3. 22. Studies on the mechanism of ATP synthesis in energy transducing systems

    Författare :Jeff Boork; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of this investigation was to study the mechanism by which ATP is phosphorylated to ATP in chromatophores, mitochondria and chloroplasts. All these particles seem to have a similar way of transducing energy liberated in the electron transport chain into the energy-rich compound ATP. LÄS MER

  4. 23. Quantum Chemical Studies of Enzymatic Reaction Mechanisms

    Författare :Bianca Manta; Fahmi Himo; Lubomir Rulisek; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; B3LYP; enzyme; cluster approach; mechanism; zinc; manganese; cytosine deaminase; ω-transaminase; dinitrogenase reductase-activating glycohydrolase; dual substrate recognition; organisk kemi; Organic Chemistry;

    Sammanfattning : Computer modeling of enzymes is a valuable complement to experiments. Quantum chemical studies of enzymatic reactions can provide a detailed description of the reaction mechanism and elucidate the roles of various residues in the active site. LÄS MER
