  2. 1. Asymmetric Catalysis : Ligand Design and Conformational Studies

    Author : Kristina Hallman; KTH; []
    Keywords : asymmetric catalysis; chiral ligand; oxazolines; conformational study; allylic substitution; polymer-bound ligands; dendritic ligands; crown ether; oxidations; palladacycle;

    Abstract : This thesis deals with the design of ligands for efficientasymmetric catalysis and studies of the conformation of theligands in the catalytically active complexes. All ligandsdeveloped contain chiral oxazoline heterocycles. READ MORE

  4. 2. Violaxanthin De-epoxidase and the Xanthophyll Cycle

    Author : Anna Gisselsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; zeaxanthin.; xanthophyll cycle; violaxanthin de-epoxidse; thylakoid; regulation; quenching; protonation; pH-dependence; light stress; histidine; Conformational change; domains; Växtbiokemi;

    Abstract : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. READ MORE

  5. 3. Improving selectivity in protein extraction by subtle interactions and environmental changes

    Author : Sheryl Fernandes; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Difference Spectroscopy; Circular dichroism; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fluorescence spectroscopy; Metal ions; Cibacron blue; Polyvinylpyrrolidone; Polyethylene glycol; Triton X-114; His 6 tag; Cold-active ß-lactamase; Cold-active ß-galactosidase; Lactate dehydrogenase; Cutinase; Affinity Extraction; Conformational change; Partial Denaturation; Molecular interaction; Aqueous two-phase systems; Detergent foam;

    Abstract : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. READ MORE

  6. 4. Structural Studies of Binding Proteins: Investigations of Flexibility, Specificity and Stability

    Author : Ulrika Magnusson; Sherry L. Mowbray; Anthony J. Wikinson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Periplasmic binding protein; X-ray crystallography; conformational change; acidophile; protein specificity; protein structure; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Binding proteins are present both in gram-negative and gram-positive bacteria. They are the recognition components of the ABC transport systems that transport different nutrients into the cell, and are in some cases also involved in chemotaxis. READ MORE

  7. 5. Insights Into Protein Synthesis - Structural Aspects of Elongation Factor G and Fusidic Acid Inhibition

    Author : Sebastian Hansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molekylär biofysik; Structure chemistry; Strukturkemi; Molecular biophysics; Biologi; Biology; Biomedicinska vetenskaper; Biomedical sciences; conformational change; fusidic acid; protein synthesis; elongation factor G; crystal structures;

    Abstract : Elongation factor G (EF-G) catalyses the translocation step in protein synthesis on the ribosome. During this event the antibiotic Fusidic acid (FA) binds to and irreversably inhibits the release of the EF-G:GDP complex from the ribosome. READ MORE
