  2. 1. The digestive machinery of a human gut bacterium : Structural enzymology of galactomannan utilisation

    Author : Viktoria Bågenholm; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Glycoside hydrolase; enzymology; structural biology; kinetics; HPLC; product profiles; structure-function;

    Abstract : Human gut bacteria utilise different types of polysaccharides present in our diet. One of these polysaccharides is galactomannan. Many organisms in the phylum Bacteroidetes have gene clusters encoding for all proteins required for hydrolysis, binding and transport of one type of polysaccharide, called polysaccharide utilisation loci (PULs).

  4. 2. Galactoglucomannan-degrading enzymes from Aspergillus niger

    Author : Pia Ademark; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Aspergillus niger; beta-mannosidase; alpha-galactosidase; purification; hydrolysis; cloning; galactoglucomannan; expression; Biochemistry; Metabolism; Biokemi;

    Abstract : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3. READ MORE

  5. 3. Enzymatic conversion of β-mannans through transglycosylation and hydrolysis : Synthesis of building blocks for novel biomaterials from renewables

    Author : Samuel Butler; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-Mannanase; Transglycosylation; Enzymatic synthesis; Glycoconjugates; Enzyme synergy; α- Galactosidase; Galactoglucomannan; Enzyme engineering; MALDI-ToF MS; HPLC;

    Abstract : The major softwood hemicellulose is galactoglucomannan (GGM), an abundant polysaccharide which constitutes up to 25% of the dry weight of wood, much of which is discarded in current refinery practices. Among the enzymes responsible for the degradation of this hemicellulose are the β-mannanases. READ MORE

  6. 4. Invasive fungal disease in immunocompromised hosts with focus on diagnostics

    Author : Helena Hammarström; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; invasive fungal disease; diagnosis; 1; 3-β-d-glucan; hematological malignancies; hematopoietic stem cell transplantation; HIV; lung transplant recipients; bronchiolitis obliterans syndrome;

    Abstract : Invasive fungal diseases (IFDs) are severe conditions affecting immunocompromised patients. The primary aim of this thesis was to explore different methods for diagnosis of IFD in different groups of immunocompromised patients. Papers I and II included patients with hematologic disorders.

  7. 5. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Author : Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Abstract : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. READ MORE
