  1. 6. Engineering Candida antarctica Lipase A for Enantioselective Transformations in Organic Synthesis : Design, Immobilization and Organic Solvent Screening of Smart Enzyme Libraries

    Författare :Ylva Wikmark; Jan-Erling Bäckvall; Romas Kazlauskas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica Lipase A; protein engineering; enzyme libraries; enzyme immobilization; biocatalysis; organisk kemi; Organic Chemistry;

    Sammanfattning : The use of enzymes as catalysts in organic synthesis constitutes an attractive alternative to conventional chemical catalysis. Enzymes are non-toxic and biodegradable and they can operate under mild reaction conditions. LÄS MER

  3. 7. Enzymatic synthesis of acrylates. Catalyst properties and development of process and product

    Författare :Mathias Nordblad; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme kinetics; process development; enzyme stability; enzyme immobilisation; acrylation; lipase;

    Sammanfattning : The increasingly apparent environmental problems in our surroundings necessitate a quest for sustainable development in all areas of human endeavour. Within the field of chemistry and the production of chemicals, the focus is increasingly on the development of green chemistry. LÄS MER

  4. 8. Mutational Analysis and Redesign of Alpha-class Glutathione Transferases for Enhanced Azathioprine Activity

    Författare :Olof Modén; Bengt Mannervik; Mikael Widersten; Kenneth Tew; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allelic variants; azathioprine; bioactivation; chimeric mutagenesis; directed evolution; DNA shuffling; enzyme engineering; glutathione transferase; GST; lysate screening; molecular docking; multiple alignment; multivariate analysis; polymorphism; principal component analysis; prodrug; prodrug activation; protein engineering; protein redesign; reduced amino acid alphabet; saturation mutagenesis; semi-rational enzyme engineering; site-directed mutagenesis; structure-activity relationship; structure-based redesign; Biokemi; Biochemistry;

    Sammanfattning : Glutathione transferase (GST) A2-2 is the human enzyme most efficient in catalyzing azathioprine activation. Structure-function relationships were sought explaining the higher catalytic efficiency compared to other alpha class GSTs. LÄS MER

  5. 9. Tripeptidyl-Peptidase II : Structure, Function and Gene Regulation

    Författare :Ann-Christin Lindås; Birgitta Tomkinson; Mikael Widersten; Ralf Morgenstern; Uppsala universitet; []
    Nyckelord :Biochemistry; gene regulation; protein expression; enzyme kinetics; tripeptidyl-peptidase II; proteasome; intracellular protein degradation; exopeptidase; Biokemi;

    Sammanfattning : The protein degradation process is of vital importance for the cell to maintain cellular functions. An important enzyme in this process is the multimeric tripeptidyl-peptidase II (TPP II). It removes tripeptides from a free N-terminus of the substrates. LÄS MER

  7. 10. Structure and function studies of GH45 glycoside hydrolases

    Författare :Laura Okmane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The enzymatic hydrolysis of lignocellulosic material in nature is carried out by a plethora of cellulases. Glycoside hydrolase family 45 (GH45) enzymes are small cellulases most commonly found in fungi that catalyse the hydrolysis of β(1→4) linked glucans. LÄS MER
