1. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology
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.

2. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides
Sammanfattning : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. LÄS MER
3. On the engineering of proteins: methods and applications for carbohydrate-active enzymes
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. Thermostable glycosidases and glycosynthases as biocatalysts in green chemistry applications
Sammanfattning : The constant need to develop environmental friendly processes using renewable raw materials and to reduce harmful waste production motivates the present investigation focusing on biocatalyst development for enzymatic synthesis, a biotechnological approach in the field of green chemistry. At first, structural functional experiments were made for a β-glucosidase from T. LÄS MER
5. Exploring the structure of oligo- and polysaccharides : Synthesis and NMR spectroscopy studies
Sammanfattning : A deeper understanding of the diversity of carbohydrates and the many applications of oligo- and polysaccharides found in nature are of high interest. Many of the processes involving carbohydrates affect our everyday life. This thesis is based on six papers all contributing to an extended perspective of carbohydrate property and functionality.
