  2. 2. Structural and biochemical analysis of two copper proteins - plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3

    Författare :Frida Jacobson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plastocyanin; X-ray crystallography; nitrite reductase; copper geometry; redox; copper protein; photosynthesis; reduction potential; denitrification; electron transfer;

    Sammanfattning : Plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3 are two copper-containing proteins that are involved in biological electron transport chains: plastocyanin operates in photosynthesis and nitrite reductase takes part in the denitrification pathway.

  3. 3. Denitrification as an adaptive trait in soil and groundwater bacteria

    Författare :Christer Bergwall; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microcosm; forest soil; aquifer; groundwater; reductase; nitrous oxide; nitric oxide; nitrite; nitrate; selection; adaptation; bacteria; nitrification; Denitrification; dissimilatory nitrate reduction to ammonium; fertiliser; 15NO3-; 15NH4 ; Ecology; Ekologi;

    Sammanfattning : The focus of the thesis is on selection and adaptation processes in bacteria with emphasis on denitrifying bacteria in groundwater. Other nitrogen transformation processes such as dissimilatory nitrate reduction to ammonium (nitrate ammonification) and nitrification of forest soil bacteria are briefly discussed. LÄS MER

  4. 4. Selective Catalytic Reduction of NOx with NH3 - Kinetic Modeling and Experimental Studies using Zeolite Based Catalysts

    Författare :Hanna Maria Sjövall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective catalytic reduction; SCR; NO reduction; Ammonia; Fe-zeolite; DRIFT; Cu-ZSM-5; Zeolite; Nitrogen oxide; Kinetic modeling;

    Sammanfattning : Emissions from the combustion of fossil fuel contain several pollutants which can be converted over a catalyst to less harmful products. An efficient way to reduce nitrogen oxides in a lean environment is to apply selective catalytic reduction of these oxides with ammonia (NH3 SCR). LÄS MER

  5. 5. Structural Plasticity and Function in Cytochrome cd1 Nitrite Reductase

    Författare :Tove Sjögren; Christian Cambillau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; cytochrome cd1; nitrite reductase; oxidase; redox protein; electron transfer; proton transfer; X-ray crystallography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Cytochrome cd1 nitrite reductase is a bifunctional enzyme, which catalyses the one-electron reduction of nitrite to nitric oxide, and the four-electron reduction of oxygen to water. The latter is a cytochrome oxidase reaction. Both reactions occur on the d1 haem iron of the enzyme. LÄS MER
