  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.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; enantioselectivity; Salen Mn III ; substrate selectivity; porphyrin; Jacobsen-Katsuki epoxidation; supramolecular catalysis; Hydrogen-bond; 2-pyridone;

    Abstract : Popular Abstract in Swedish Inom kemin kan uppbyggnaden av molekylära aggregat styras genom att använda sig av kovalenta bindningar eller genom att utnyttja svaga växelverkningar. Den moderna kemin baseras på många års grundforskning på reaktionsförlopp där bildningen av en kovalent bindning stått i fokus vilket har gjort det möjligt att förutsäga utfallet av en sådan reaktion.

  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. Exploring Selectivity and Hysteresis Kinetic Studies on a Potato Epoxide Hydrolase

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Diana Lindberg; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; regioselectivity; selectivity; hysteresis; conformational changes; cooperativity; deep eutectic solvents; methylstyrene oxide; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Biokemi; Biochemistry;

    Abstract : The kinetic mechanism of an α/β hydrolase fold epoxide hydrolase from potato, StEH1, has been studied with the aims of explaining the underlying causes for enantio- and regioselectivity, both being important for product purity. Further effort has been laid upon understanding the causes of a hysteretic behavior discovered in the measurements leading to Paper I. READ MORE
