  2. 6. 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

  4. 7. Exploring and exploiting plant biomass degradation by Bacteroidetes

    Author : Cathleen Kmezik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polysaccharide utilization locus; plant biomass degradation; carbohydrate esterases; multidomain enzymes; Bacteroidetes; PUL transfer; carbohydrate-active enzymes; xylan;

    Abstract : Bacteroidetes bacteria have evolved to become excellent biomass degraders. They achieved this by applying carbohydrate-active enzymes (CAZymes) and organizing genes connected to the degradation of specific polysaccharides into discrete gene cassettes, so-called polysaccharide utilization loci (PULs).

  5. 8. Production and investigation of highly thermophilic multi-domain carbohydrate-active enzymes

    Author : Daniel Krska; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure; xylanase; carbohydrate esterase; multidomain enzymes; carbohydrate-active enzymes; thermostable enzymes; plant biomass degradation; Caldicellulosiruptor;

    Abstract : With the looming threat of climate change caused largely by an excess of carbon dioxide in the atmosphere, recent scientific efforts have focused on the substitution of fossil fuels and other polluting compounds with more environmentally conscious choices. To this end, the investigation of biomass as both a renewable source of energy and as a chemical basis to produce high-value products is being extensively investigated. READ MORE

  6. 9. Dissecting function and catalytic mechanism of fungal lytic polysaccharide monooxygenases

    Author : Bing Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fungi use a complex and well-orchestrated enzyme machinery to degrade lignocellulose biomass, in which both hydrolytic and redox enzymes are involved. Lytic polysaccharide monoxygenases (LPMOs) are copper-dependent enzymes that cleave bonds in polysaccharides using oxidative mechanisms. READ MORE

  7. 10. In vivo and in vitro models for determination of antiviral activity and resistance

    Author : Ewa Ljungdahl Ståhle; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The AIDS epidemic has been the driving force for the discovery of substances that inhibit the replication of human immunodeficiency virus (HIV). Much interest has earlier focused on a single gene product central to the life cycle of HIV and to all other retroviruses: the reverse transcriptase (RT), the enzyme responsible for synthesis of DNA from viral RNA.
