  2. 21. Structural studies on aerobic and anaerobic respiratory complexes

    Author : Susanna Törnroth; Lars Hederstedt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : All respiratory pathways, whether aerobic or anaerobic, are based on formation of an electrochemical proton gradient called proton motive force (pmf) that drives ATP formation. Membrane-bound respiratory complexes translocate protons across the membrane from a region of low [H+] and negative electrical potential to a region of high [H+] and positive electrical potential.

  4. 22. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

    Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. READ MORE

  5. 23. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes

    Author : Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE

  6. 24. Structure and function of the presynaptically neurotoxic phospholipase A² from the Australian tiger snake - Notechis scutatus scutatus

    Author : Bengt Westerlund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Notexin is a member of the phospholipase A2, (PLA2) family of proteins. Despitethe fact they are homologous proteins with similar sequence and almost identicalstructures, they show an impressing diversity of functions. READ MORE

  7. 25. New approaches in biomembrane chromatomatography and microchromatographic techniques

    Author : Cheng-Ming Zeng; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Development of methods for rendering chromatography more applicable to studies in lifesciences remains an area of active research. In the present work, new methods inbiomembrane chromatography and microchromatographic techniques have been developedand applied successfully to quantitative analysis of biological interactions and separations ofproteins on a micro-scale.
