  1. 21. Protein Surfaces Probed by Aqueous Two-phase Partitioning

    Författare :Kristina Berggren; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; partitioning; Aqueous two-phase systems; protein surface; peptide; Biochemistry; amino acid residue; Biokemi;

    Sammanfattning : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. LÄS MER

  3. 22. Mitochondrial Energy Metabolism : Kgd4 is a novel subunit of the α-ketoglutarate dehydrogenase complex

    Författare :Manfred Heublein; Martin Ott; Flavia Fontanesi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; α-ketoglutarate dehydrogenase; Kgd4; Krebs cycle; Biochemistry; biokemi;

    Sammanfattning : Mitochondria are essential organelles of eukaryotic cells and are responsible for their energy metabolism. The citric acid cycle, a chain of redox reactions in the mitochondrial matrix, is a central metabolic hub. LÄS MER

  4. 23. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity

    Författare :Marie Andersson; Ingvar Brandt; Cynthia de Wit; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; BMAA; beta-N-methylamino-L-alanine; milk; secretion; amino acid transporter; autoradiography; metabolism; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Sammanfattning : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. LÄS MER

  5. 24. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases

    Författare :Ellenor Devine; Peter Lindblad; Karin Stensjö; Laurent Cournac; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; hydrogenase; hydrogenase specific protease; maturation; regulation; transcriptional studies; hupW; hoxW; hyp; NtcA; CalA; Biology; Biologi; Molecular biology; Molekylärbiologi; Microbiology; Mikrobiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. LÄS MER

  7. 25. Characterization of a new amino acid transport system in human epidermal Langerhans cells

    Författare :Niels Bendsöe; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amino acid transport; energy charge; epidermis; glycolysis; lactate; Langerhans cells; L-dopa; mitochondria; omeprazole; Dermatology; venereology; Dermatologi; venereologi;

    Sammanfattning : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. LÄS MER
