  1. 11. Cu(I) stabilizing polymers for marine anti-fouling applications

    Author : Alireza Movahedi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; coordinating polymers; copper; anti-fouling coatings; CuAAC; triazole; epoxide.; polymer functionalization; click chemistry;

    Abstract : The growth of marine organisms on immersed surfaces in seawater is known as biofouling and causes several problems for marine transportation. The need to combat fouling is thus of great importance. Copper has to be used in extreme amounts to act as an efficient biocide. READ MORE

  2. 12. Nitrile Hydratases and Epoxide-Transforming Enzymes : Quantum Chemical Modeling of Reaction Mechanisms and Selectivities

    Author : Kathrin Hopmann; Fahmi Himo; Nigel G. Richards; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Quantum chemical studies of enzymatic reactions are able to provide detailed insight into mechanisms and catalytic strategies. The energetic feasibility of proposed mechanisms can be established, and new possible reaction pathways can be put forward. READ MORE

  3. 13. Structure-function studies of epoxide hydrolases

    Author : Agata Naworyta; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Epoxides are three-membered cyclic ethers formed in cells via several metabolic pathways. Epoxide hydrolases (EHs) are enzymes that hydrolyse epoxides to the corresponding diols. The main goal of this thesis was to investigate the structures of EHs from the alpha/beta-hydrolase family. READ MORE

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

    Author : Diana Lindberg; Mikael Widersten; Gunnar Johansson; Richard N. Armstrong; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; regioselectivity; selectivity; hysteresis; conformational changes; cooperativity; deep eutectic solvents; methylstyrene oxide; Biochemistry; 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

  5. 15. Quantum chemical studies of epoxide-transforming enzymes

    Author : Kathrin H. Hopmann; Hans Ågren; Margareta Blomberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Density functional theory is employed to study the reaction mechanisms of different epoxide-transforming enzymes. Calculations are based on quantum chemical active site models, which are build from X-ray crystal structures. The models are used to study conversion of various epoxides into their corresponding diols or substituted alcohols. READ MORE
