1. 1. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

   Författare :Zubaida Gulshan Kazi; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

   Sammanfattning : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. LÄS MER

3. 2. Exploring glycoside hydrolase family 5 (GH5) enzymes

   Författare :Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
   Nyckelord :GH5; glycoside hydrolase; subfamily classification; mannans; polysaccharides; mannanases; cell wall; GH5; glykosidhydrolas; subfamiljklassificering; mannaner; polysackarider; mannanaser; cellvägg; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Sammanfattning : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. LÄS MER

4. 3. 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

5. 4. Exploring thermostable glycoside hydrolases: Amylases and beta-glucosidases

   Författare :Pernilla Turner; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Proteiner; beta-glucosidase; thermostability; activity; cyclodextrinase; enzymology; crystallization; enzymologi; expression; glycoside hydrolase; Proteins; transglycosylation;

   Sammanfattning : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. LÄS MER

7. 5. Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides

   Författare :Pontus Lundemo; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glycoside hydrolases; Cyclodextrin glucanotransferases; β-glucosidases; Alkyl glycosides; Thermotoga neapolitana; Organic reaction media;

   Sammanfattning : To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. LÄS MER
