  1. 1. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Författare :Zubaida Gulshan Kazi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

    Sammanfattning : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. LÄS MER

  3. 2. On the engineering of proteins: methods and applications for carbohydrate-active enzymes

    Författare :Fredrika Gullfot; Harry Brumer; Antoni Planas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme engineering; rational design; directed evolution; DNA shuffling; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; carbohydrate binding module; polysaccharide synthesis; Bioengineering; Bioteknik;

    Sammanfattning : This thesis presents the application of different protein engineering methods on enzymes and non-catalytic proteins that act upon xyloglucans. Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glucans in the cell wall of plants. LÄS MER

  4. 3. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology

    Författare :Fredrika Gullfot; Harry Brumer; Tuula Teeri; Jerry Ståhlberg; Mats Martinelle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; polysaccharide synthesis; Bioengineering; Bioteknik; Enzyme engineering; Enzymteknik; Bioorganical synthesis; Bioorganisk syntes; Biomaterials; Biomaterial;

    Sammanfattning : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.
