1. 1. Enantioselective Binding of Designed Propranolol Analogues to the Cellobiohydrolase Cel7A

   Författare :Alexandra Fagerström; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strukturkemi; Structure chemistry; enzymologi; Proteiner; enzymology; Proteins; Naturvetenskap; Natural science; capillary electrophoresis; chiral recognition; enantiomeric selectivity; cellobiohydrolase Cel7A; propranolol; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. LÄS MER

3. 2. Degradation of wood polysaccharides by fungal glycoside hydrolases

   Författare :Torny Eriksson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Penicillium brasilianum; ethanol; cellulose; wood polysaccharides; Man5A hemicellulase; cellulase; endoglucanase; cellobiohydrolase; Cel7B; Cel7A; Trichoderma reesei; glycoside hydrolase; Plant biochemistry; Växtbiokemi;

   Sammanfattning : The enzymatic degradation of wood polysaccharides such as cellulose and hemicellulose is an important process in nature. In addition, cellulases and hemicellulases can be used in industrial applications. Fuel ethanol can potentially be produced from wood by enzymatic hydrolysis of cellulose followed by yeast fermentation of the formed sugars. LÄS MER

4. 3. Heterogeneous Adsorption in Chiral LC

   Författare :Gustaf Götmar; Attila Felinger; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : The adsorption of chiral drugs on proteins immobilized on silica shows an heterogeneous adsorption behavior on multiple sites. The theory of nonlinear chromatography was used for a systematic study on this behavior - linear chromatography can only measure the "global" retention. LÄS MER

5. 4. Structure-function studies of GH7 cellulases, key enzymes in the global carbon cycle

   Författare :Topi Haataja; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Enzyme mixtures used for lignocellulosic ethanol production are most commonly derived from filamentous fungi, and enzymes from the glycoside hydrolase family 7 (GH7) constitute the most abundant components in these cocktails. In this thesis I have aimed to increase our understanding of this enzyme family, with focus on the interrelation between their structure and function. LÄS MER

7. 5. Hydrolytic and Oxidative Mechanisms Involved in Cellulose Degradation

   Författare :Anu Nutt; Jerry Ståhlberg; Henrik Stålbrand; Uppsala universitet; []
   Nyckelord :Biochemistry; cellobiohydrolase; cellulase; cellulose; cellobiose dehydrogenase; endoglucanase; kinetics; synergism; competitive binding; Biokemi;

   Sammanfattning : The enzymatic degradation of cellulose is an important process in nature. This thesis has focused on the degradation of cellulose by enzymes from two cellulose-degrading fungi, Hypocrea jecorina and Phanerochaete chrysosporium, including both the action of the individual enzymes and their synergistic interplay.
