21. Enzyme selectivity as a tool in analytical chemistry
Sammanfattning : Enzymes are useful tools as specific analytical reagents. Two different analysis methods were developed for use in the separate fields of protein science and organic synthesis. Both methods rely on the substrate specificity of enzymes. Enzyme catalysis and substrate specificity is described and put in context with each of the two developed methods. LÄS MER
22. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases
Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

23. Tunnels and Grooves : Structure-Function Studies in Two Disparate Enzymes
Sammanfattning : This thesis describes structural and binding studies in enzymes from two different organisms: ribonucleotide reductase from Mycobacterium tuberculosis (RNR) and lipase A from Candida antarctica (CalA).RNR is viable as a target for new drugs against the causative agent of tuberculosis.

24. Enzymes as catalysts in synthesis of enantiomerically pure building blocks : secondary alcohols bearing two vicinal stereocenters
Sammanfattning : Enzymes as tools in organic synthesis have provided enormous advantages. This thesis deals with the applications of enzymes in the kinetic resolutions of racemic compounds. The stereochemistry of chiral compounds and the kinetics of α/β hydrolase lipases are presented. LÄS MER
25. Building blocks for polymer synthesis by enzymatic catalysis
Sammanfattning : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. LÄS MER
