6. Towards Classification and Functional Description of Enzymes: A case study of feruloyl esterases
Sammanfattning : The prediction of enzyme functionality from sequence or structure data remains a challenging task that can be best addressed by studying the structure-function relationships determined from previously available information. This thesis work was focused on developing a reliable classification and functional description for the feruloyl esterase (FAE) enzyme family, whose members’ possess both structural and catalytic promiscuity.

7. Phage–derived Endolysins as Potential Antibacterials : A Study of Peptidoglycan Hydrolase and Mycolylarabinogalactan Esterase Enzymes
Sammanfattning : Bacteriophages, or phages, are viruses that infect bacteria, at the end of their life cycle produce a set of enzymes called endolysins to lyse host cells from within, facilitating the release of the viral progeny. Due to their lytic activity, endolysins have gained great interest as potential antibacterials targeting both Gram–positive and –negative bacteria, especially in the actual context of increasing rates of antibiotics resistance.

8. Chromatographic Studies of Solute Interactions with Immobilized Red Blood Cells and Biomembranes
Sammanfattning : Specific and non-specific interactions of solutes with immobilized biomembranes were studied using chromatographic methods. Liposomes, proteoliposomes and red blood cell (RBC) membrane vesicles were immobilized by a freeze-thawing procedure, whereas whole RBCs were adsorbed in the gel beds using electrostatic interaction, binding to wheat germ agglutinin (WGA) or the streptavidin-biotin interaction.

9. Towards Understanding of Selectivity & Enantioconvergence of an Epoxide Hydrolase
Sammanfattning : Epoxide hydrolase I from Solanum tuberosum (StEH1) and isolated variants thereof has been studied for mapping structure-function relationships with the ultimate goal of being able to in silico predict modifications needed for a certain activity or selectivity. To solve this, directed evoultion using CASTing and an ISM approach was applied to improve selectivity towards either of the enantiomeric product diols from (2,3-epoxypropyl)benzene (1). LÄS MER
10. Artificial Photosynthesis: Molecular Catalysts for Water Oxidation
Sammanfattning : Artificial photosynthesis provides a promising solution to the future sustainable energy system. Water is the only suitably sufficient protons and electrons supplier by the reaction of water oxidation. However, this reaction is both kinetically and thermodynamically demanding, leading to a sluggish kinetics unless the introduction of a catalyst. LÄS MER
