1. Biological role and technical application of xyloglucan endotransglycosylase and xyloglucan
Sammanfattning : .... LÄS MER
2. Design and synthesis of xyloglucan oligosaccharides : structure-function studies and application of xyloglucan endotransglycosylase PttXET16A
Sammanfattning : Primary cell walls are a composite of cellulose microfibrilsand hemicelluloses. Xyloglucan is the principal hemicelluloseof primary cell walls of dicotyledons. Xyloglucanendotransglycosylases (XETs) cleave and religate xyloglucanpolymers in plant cell walls. LÄS MER
3. Structural Studies of a Xyloglucan Endotransglycosylase from Populus tremula x tremuloides and Three Conserved Hypothetical Proteins from Mycobacterium tuberculosis
Sammanfattning : This thesis describes the structural studies of four different proteins from two organisms. Xyloglucan endotransglycosylases, XETs, are involved in plant cell wall expansion and remodeling by splitting and reconnecting xyloglucan-cellulose crosslinks. The first crystal structure of a XET enzyme has been determined to 1.8 Å. LÄS MER
4. Heterologous expression and characterization of xyloglucan endotransglycosylases from Populus tremula x tremuloides
Sammanfattning : Xyloglucan endotransglycosylases (XETs) are enzymes involvedin the reorganization of the primary cell wall. This thesisdescribes several aspects of XET16A from hybrid aspen (Populustremula x tremuloides). The gene was isolated from the hybridaspen cDNA library and the protein was expressed heterologouslyin the methylotrophic yeast Pichia pastoris. LÄS MER
5. Design of enzymatic systems for the modification of cellulose fiber surfaces
Sammanfattning : This thesis describes the design of enzymatic systems forthe modification of cellulose fiber surfaces. A single-enzymeapproach employed a conjugate between theNeocallimastix patriciarumCel6A cellulose-bindingmodule and lipase B fromCandida antarctica(CBM-CALB) to enhance theaccessibility of the enzyme to the target hydroxyl groups.
