  1. 11. A kinetic study of metabolite transfer in coupled two-enzyme reactions

    Författare :Henrik Pettersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Free diffusion; Enzyme kinetics; Channelling; Dehydrogenase; Fusion protein; Biochemistry; Proximity effect; metabolism; Biokemi;

    Sammanfattning : There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion.

  3. 12. Efficient Conversion of Lignocellulose Hydrolysates- Yeast Tolerance and Redox Metabolism

    Författare :Tobias Modig; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metabolism; Biokemi; metabolism; hyperosmotic stress; Biochemistry; S. cerevisiae; anaerobic growth; inhibitor tolerance; furfural; lignocellulose; HMF; Biotechnology; Bioteknik;

    Sammanfattning : The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. LÄS MER

  4. 13. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex

    Författare :Cecilie Mathiesen; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; mrp; electron transport; respiration; membrane protein;

    Sammanfattning : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. LÄS MER

  5. 14. Sources of Arachidonic Acid in Platelets, Bone, Marrow and Gastrointestinal Tract

    Författare :Li Zhou; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phospholipids; Megakaryocyte; Lysophosphatidylcholine; Lipoproteins; Linoleic acid; Intralipid; Interconversion; Gastrointestinal tract; Plasma free fatty acids; Fasting; Dietary fatty acids; Desaturase; Cholesterol; Chylomicron remnant; Chylomicron; Arachidonic acid; Bone marrow; Platelets; Protein S; Prothrombin; Triglycerides.; Biochemistry; Metabolism; Biokemi; metabolism;

    Sammanfattning : This study investigates pathways by which the eicosanoid precursor pools in the platelets, bone marrow and the gastrointestinal (GI) mucosa are acquired and regulated, and in this context some aspects on the interaction between triglyceride (TG)-rich lipoproteins and platelets. 1.

  7. 15. Superporous agarose a new material for chromatography

    Författare :Per-Erik Gustavsson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein separations; Chromatography; Superporous agarose; Continuous agarose beds; Intraparticle convection; Pore flow; Biochemistry; Metabolism; Biokemi; metabolism; Biotechnology; Bioteknik;

    Sammanfattning : Agarose, the most commonly employed chromatography base material in industrial purification processes for biomolecules – proteins, has almost ideal properties. The major disadvantage of the agarose support is its poor mechanical strength which excludes its use in high speed separations where small particles are needed in order to achieve improved chromatographic efficiency.
