  1. 1. Structure and Function of Beta-Mannanases from Glycoside Hydrolase Clan A. A Study of Hemicellulases from Microbes and a Mollusc

    Författare :Lars Anderson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; enzymology; Proteins; subsite organisation; transglycosylation; enzyme kinetics; beta-mannanase; hemicellulose;

    Sammanfattning : Hemicellulose is the second most abundant group of renewable polysaccharides. Mannans can be found as the major hemicellulose in softwood and as storage polysaccharides in a range of plants. In this work, structural and functional characterisations of family 5 and 26 endo-1,4-b-mannanases (b-mannanases) have been performed. LÄS MER

  3. 2. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

    Författare :Alexandra Andersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

    Sammanfattning : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. LÄS MER

  4. 3. Membrane protein proteomics - Novel method for membrane protein identification and quantification

    Författare :Maria Bentz; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemisk teknik; mebran; steroider; Lipider; membranes; steroids; Lipids; enzymologi; Proteiner; Membrane proteins; Proteomics; Proteinase K; N-terminal labelling; Relative Quantitation; Database search; Cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; enzymology; Proteins; Biochemical technology;

    Sammanfattning : Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. LÄS MER

  5. 4. Rate Limiting Factors For Protein Folding

    Författare :Maria Berggård Silow; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetic competition; transient aggregation; diffusion control; reconfiguration time; collapse; osmolytes; broad barriers; Hammond behaviour; two-state; U1A; CI2; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : Abstract. This thesis describes factors that are rate limiting for the folding of two small proteins, U1A and CI2 which fold without accumulating intermediates. The [GdnHCl] dependencies of the unfolding- and refolding kinetics of U1A display downward curvatures. LÄS MER

  7. 5. Structure and distribution of alpha-1-microglobulin proteins

    Författare :Tord Berggård; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteins; lysine; chromophore; placenta; immunohistochemistry; albumin; prothrombin; plasma; bikunin; lipocalin; alpha-1-microglobulin; protein HC; enzymology; Proteiner; enzymologi;

    Sammanfattning : This thesis describes studies of the structure and tissue distribution of alpha-1-microglobulin (a1-m), a member of the lipocalin protein superfamily with immunosuppressive properies. It was shown that a1-m appears in human plasma in five major forms. LÄS MER
