1. 1. NMR studies of DNA/RNA-binding proteins

   Författare :Helena Berglund; KTH; []
   Nyckelord :;

   Sammanfattning : This thesis concerns the structure and internal dynamics inDNA and RNA-binding proteins. While it has long been known thata proper three-dimensional structure is essential for aprotein's ability to interact with other biomolecules, theinfluence of the inherent protein dynamics is less wellunderstood.

3. 2. The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats

   Författare :Helena Berglund; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; threats; distribution range; isolation; endemism; invasions; invaders; vulnerability; non indigenous species; rarity; threatened species;

   Sammanfattning : We live in a globalised world where people and goods travel large distances. Various species are brought along on these journeys, intentionally or as hitchhikers. Some of these species establish populations in regions to which they could not have spread without human assistance, and where they are considered to be non indigenous species (NIS). LÄS MER

4. 3. Electron and Energy Transfer in Supramolecular Complexes Designed for Artificial Photosynthesis

   Författare :Helena Berglund Baudin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; artificial photosynthesis; electron transfer; energy transfer; ruthenium; manganese; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : In the society of today the need for alternative energy sources is increasing. The construction of artificial devices for the conversion of sunlight into electricity or fuel seems very attractive from an environmental point of view, since these devices are based on processes that does not necessarily generate any harmful biproducts.

5. 4. Rational and combinatorial genetic engineering approaches for improved recombinant protein production and purification

   Författare :Nina Bandmann; Per-Åke Nygren; Helena Berglund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aqueous two-phase system; combinatorial library; expression vector; flow cytometry; fusion tag; partitioning; peptide library; phage display; recombinant proteins; ribosomal binding site; translation initiation; Bioengineering; Bioteknik;

   Sammanfattning : The bacterium Escherichia coli (E. coli) is in many situations an ideal host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve sufficiently high product quantities. LÄS MER

7. 5. Structural and functional studies of the secreted metalloprotease PrtV from Vibrio cholerae

   Författare :Aaron Edwin; Elisabeth Sauer-Eriksson; Helena Berglund; Umeå universitet; []
   Nyckelord :Cholera; Vibrio cholerae; virulence factors; PrtV; X-ray crystallography; NMR;

   Sammanfattning : Cholera, an acute diarrheal diseases caused by the intestinal infection of the pathogenic bacterium Vibrio cholerae, continues to be a global killer in the world today. PrtV, a secreted zinc metalloprotease, is a potent cytotoxic virulence factor of V. cholerae. LÄS MER
