1. Characterization and engineering of carbohydrate-active enzymes for biotechnological applications
Abstract : Extremozymes are enzymes produced by microorganisms that live in extreme habitats. Due to their higher stability, extremozymes is attracting interest as biocatalysts in various industrial processes. In this context, carbohydrate-active extremozymes can be used in various processes relevant to the paper, food and feed industry. READ MORE

2. From Time-Averaged to Time-Resolved Crystallography: Studies on Superoxide Dismutase and Myoglobin
Abstract : We have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. READ MORE

3. Advancements in Firefly Luciferase-Based Assays and Pyrosequencing Technology
Abstract : Pyrosequencing is a new DNA sequencing method relying on thesequencing-by-synthesis principle and bioluminometric detectionof nucleotide incorporation events. The objective of thisthesis was improvement of the Pyrosequencing method byincreasing the thermal stability of firefly luciferase, and byintroducing an alternative DNA polymerase and a new nucleotideanalog.

4. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity
Abstract : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. READ MORE

5. Exploring thermostable glycoside hydrolases: Amylases and beta-glucosidases
Abstract : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. READ MORE
