  1. 1. Characterization and Directed Evolution of an Alcohol Dehydrogenase A Study Towards Understanding of Three Central Aspects of Substrate Selectivity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Emil Hamnevik; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alcohol dehydrogenase; ADH-A; Biocatalysis; Directed evolution; Enantioselectivity; Enzyme kinetics; Enzyme mechanisms; Protein Engineering; Regioselectivity; Substrate selectivity; Biokemi; Biochemistry;

    Abstract : Many different chemicals are used in the everyday life, like detergents and pharmaceuticals. However, their production has a big impact on health and environment as much of the raw materials are not renewable and the standard ways of production in many cases includes toxic and environmentally hazardous components.

  3. 3. Investigation of Kinetically Labile Supramolecu-lar System Addressing Substrate Selectivity in the Catalytic Epoxidations of Olefins

    University dissertation from Organic Chemistry, Lund University

    Author : Fabrice Odille; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; enantioselectivity; Salen Mn III ; substrate selectivity; porphyrin; Jacobsen-Katsuki epoxidation; supramolecular catalysis; Hydrogen-bond; 2-pyridone;

    Abstract : This thesis is devoted to the development and investigation of a supramolecular system used to catalyze Jacobsen-Katsuki epoxidations with the aim to attain substrate selectivity without product inhibition. The supramolecular catalyst is composed of two well-defined entities or units: a catalytic and a receptor. READ MORE

  4. 4. Building blocks for polymer synthesis by enzymatic catalysis

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Stefan Semlitsch; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enzyme; Enzyme Engineering; Biocatalysis; Lipase; CalB; MsAcT; Substrate specificity; Selectivity; Polymer Chemistry; Polymer Synthesis; Biotechnology; Bioteknologi;

    Abstract : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. READ MORE

  5. 5. Enzyme catalysis towards bio-based UV-curable buildingblocks

    University dissertation from Stockholm : KTH Royal Institute of Technology
