21. The Importance of Being Promiscuous : Understanding enzyme function, specificity, and evolution through structure
Sammanfattning : Enzymes are known to be amazingly specific and efficient catalysts. However, many enzymes also have so-called promiscuous functions, i.e., they are able to catalyze other reactions than their main one. LÄS MER
22. Theoretical modeling of metal- and enzyme catalyzed transformations
Sammanfattning : This thesis is focused on describing and predicting catalytic reactions. The major part of the work is based on density functional theory (DFT). In some cases where the size of the investigated system precluded the use of more accurate methods molecular dynamics was employed. LÄS MER
23. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes
Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER
24. Engineering Candida antarctica Lipase A for Enantioselective Transformations in Organic Synthesis : Design, Immobilization and Organic Solvent Screening of Smart Enzyme Libraries
Sammanfattning : The use of enzymes as catalysts in organic synthesis constitutes an attractive alternative to conventional chemical catalysis. Enzymes are non-toxic and biodegradable and they can operate under mild reaction conditions. LÄS MER
25. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection
Sammanfattning : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. LÄS MER
