  1. 1. Plant and microbial xyloglucanases: Function, Structure and Phylogeny

    Author : Jens Eklöf; Harry Brumer; Harry Gilbert; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; xyloglucan; xyloglucanases; XTH; XET; XEH; endoglucanases; EG16; Molecular biology; Molekylärbiologi;

    Abstract : In this thesis, enzymes acting on the primary cell wall hemicellulose xyloglucan are studied.  Xyloglucans are ubiquitous in land plants which make them an important polysaccharide to utilise for microbes and a potentially interesting raw material for various industries. READ MORE

  2. 2. Surface modification of cellulose materials : from wood pulps to artificial blood vessels

    Author : Lage Ahrenstedt; Harry Brumer; Lars Wågberg; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : This thesis describes the improvement of two radically different cellulose materials, paper and artificial blood vessels, constructed from two diverse cellulose sources, wood pulp and Acetobacter xylinum. The improvement of both materials was possible due to the natural affinity of the hemicellulose xyloglucan for cellulose. READ MORE

  3. 3. Xyloglucan-active enzymes : properties, structures and applications

    Author : Martin J. Baumann; Tuula T. Teeri; Harry Brumer; Vincent Eijsink; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xyloglucan; xyloglucan endo-transglycosylase hydrolase; xyloglucan endo-hydrolase; xyloglucan endo-transglycosylase; XET; xyloglucan oligosaccharides; synthesis; carbohydrate; cellulose; crystal structure; fiber; surface modification; Populus tremula x Populus tremuloides; Hybrid aspen; nasturtium; NXG; Biochemistry; Biokemi;

    Abstract : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. READ MORE

  4. 4. A holistic approach to understanding CAZy families through reductionist methods

    Author : Jens Eklöf; Harry Brumer; Per-Åke Nygren; Lars Arvestad; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Carbohydrate esterase family 8; XET; PME; YbhC; Biochemistry; Biokemi;

    Abstract :   In a time when the amount of biological data present in the public domain is becoming increasingly vast, the need for good classification systems has never been greater. In the field of glycoscience the necessity of a good classification for the enzymes involved in the biosynthesis, modification and degradation of polysaccharides is even more pronounced than in other fields.

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

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

    Abstract : 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. READ MORE
