  2. 16. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia

    Author : Thomas M. Claybourn; Lars E. Holmer; Glenn A. Brock; Christian B. Skovsted; Graham Budd; David Harper; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Biostratigraphy; Systematics; East Antarctica; Small Shelly Fossils;

    Abstract : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. READ MORE

  5. 18. Protein Engineering of Candida antarctica Lipase A : Enhancing Enzyme Properties by Evolutionary and Semi-Rational Methods

    Author : Anders G. Sandström; Jan-Erling Bäckvall; Uwe T. Bornscheuer; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; protein engineering; directed evolution; kinetic resolution; structural biology; Enzyme engineering; Enzymteknik; organisk kemi; Organic Chemistry;

    Abstract : Enzymes are gaining increasing importance as catalysts for selective transformations in organic synthetic chemistry. The engineering and design of enzymes is a developing, growing research field that is employed in biocatalysis. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 20. Exploring Conjugate Addition Activity in Pseudozyma antarctica Lipase B

    Author : Maria Svedendahl; Per Berglund; Olof Ramström; Amelie Eriksson Karlström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B · conjugate addition · enzyme catalysis · enzyme catalytic promiscuity · molecular modeling; Biochemistry; Biokemi;

    Abstract : Multifunctional enzymes have alternative functions or activities, known as “moonlighting” or “promiscuous”, which are often hidden behind a native enzyme activity and therefore only visible under special environmental conditions. In this thesis, the active-site of Pseudozyma (formerly Candida) antarctica lipase B was explored for a promiscuous conjugate addition activity. READ MORE
