21. Separation Methods in Membrane Proteomics -Integration of Aqueous Two-Phase Partitioning for Enrichment and Pre-Fractionation
Sammanfattning : The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes.

22. Enantioselective Binding of Designed Propranolol Analogues to the Cellobiohydrolase Cel7A
Sammanfattning : This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. LÄS MER
23. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways
Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER
24. Beta-Glycosidases from Hyperthermophiles as Biocatalysts
Sammanfattning : The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. LÄS MER
25. Diversity of thermostable DNA enzymes from Icelandic hot springs
Sammanfattning : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. LÄS MER
