1. Discovery and investigation of glycoside hydrolase family 5 enzymes with potential use in biomass conversion
Sammanfattning : Glycoside hydrolases (GHs) cleave glycosidic bonds in glycoconjugates, oligosaccharides and polysaccharides such as cellulose and various hemicelluloses. Mannan is a major group of hemicelluloses. LÄS MER
2. Structural Studies of Three Glycosidases
Sammanfattning : Glycosidases hydrolyse the glycosidic bond in carbohydrates. Structural studies of three glycosidases with different substrate specificities are presented in this work.Dextranase catalyzes the hydrolysis of α-1,6-glycosidic linkage in dextran polymers. LÄS MER
3. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential
Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER
4. Mannan-hydrolysis by hemicellulases: enzyme-polysaccharide interaction of a modular beta-mannanase
Sammanfattning : The enzymatic degradation of plant polysaccharides is a process of fundamental importance in nature which involves a wide range of enzymes. In this work, the structure and function of hemicellulose-degrading enzymes was investigated. The focus was on a beta-mannanase (TrMan5A) produced by the filamentous fungus Trichoderma reesei.

5. Transglycosylation catalyzed by β-mannanases : Molecular aspects relevant for enzymatic synthesis
Sammanfattning : β-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. LÄS MER
