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

   Författare :Fabrice Odille; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; enantioselectivity; Salen Mn III ; substrate selectivity; porphyrin; Jacobsen-Katsuki epoxidation; supramolecular catalysis; Hydrogen-bond; 2-pyridone;

   Sammanfattning : 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. LÄS MER

3. 27. Substrate water binding to the oxygen-evolving complex in photosystem II

   Författare :Håkan Nilsson; Johannes Messinger; Wolfgang Schröder; Robert L. Burnap; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photosynthesis; Photosystem II; water oxidation; oxygen evolution; substrate water exchange; membrane-inlet mass spectrometry;

   Sammanfattning : Oxygenic photosynthesis in plants, algae and cyanobacteria converts sunlight into chemical energy. In this process electrons are transferred from water molecules to CO2 leading to the assembly of carbohydrates, the building blocks of life. LÄS MER

4. 28. Catalysis by theta-class glutathione transferases : Substrate binding, product formation and product release

   Författare :Per Jemth; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Glutathione transferases (GSTs) are detoxication enzymes that catalyze theconjugation of glutathione to a large number of electrophilic molecules. In this waythey help to rid cells of potentially toxic substances. This thesis deals with thecatalysis afforded by Theta-class glutathione transferases. LÄS MER
