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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Discovery and investigation of glycoside hydrolase family 5 enzymes with potential use in biomass conversion

    Author : Yang Wang; Henrik Aspeborg; Ines Ezcurra; Jerry Ståhlberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plant cell wall; biomass; hemicellulose; mannans; glycoside hydrolase; subfamily classification; Arabidopsis; mannanase; transglycosylase; enzymatic characterization.; Bioteknologi; Biotechnology;

    Abstract : Glycoside hydrolases (GHs) cleave glycosidic bonds in glycoconjugates, oligosaccharides and polysaccharides such as cellulose and various hemicelluloses. Mannan is a major group of hemicelluloses. READ MORE

  6. 4. Degradation of wood polysaccharides by fungal glycoside hydrolases

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
