  2. 21. Separation Methods in Membrane Proteomics -Integration of Aqueous Two-Phase Partitioning for Enrichment and Pre-Fractionation

    Author : Henrik Everberg; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteins; metabolism; Biokemi; Metabolism; Biochemistry; Aqueous two-phase partitioning; enzymology; Proteiner; enzymologi; Proteomics;

    Abstract : The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes.

  4. 22. Enantioselective Binding of Designed Propranolol Analogues to the Cellobiohydrolase Cel7A

    Author : Alexandra Fagerström; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strukturkemi; Structure chemistry; enzymologi; Proteiner; enzymology; Proteins; Naturvetenskap; Natural science; capillary electrophoresis; chiral recognition; enantiomeric selectivity; cellobiohydrolase Cel7A; propranolol; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. READ MORE

  5. 23. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    Author : Daniela Geisler; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Abstract : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. READ MORE

  6. 24. Beta-Glycosidases from Hyperthermophiles as Biocatalysts

    Author : Therese Hansson; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biochemical technology; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi; Biotechnology; high temperatures; water activity; activity; selectivity; hexanol; hexyl-b-glycoside; galacto-oligosaccharides; lactose; hyperthermostable b-glycosidase; hydrolysis; optimisation; transglycosylation;

    Abstract : The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. READ MORE

  7. 25. Diversity of thermostable DNA enzymes from Icelandic hot springs

    Author : Sigridur Hjorleifsdottir; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermophiles; microbial diversity; SSU rRNA; Thermus; hot springs; Biotechnology; Bioteknik; Biochemistry; enzymologi; Proteiner; enzymology; metabolism; Proteins; DNA enzymes; Biokemi;

    Abstract : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. READ MORE
