1. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins
Abstract : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. READ MORE

2. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k
Abstract : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. READ MORE

3. Unveiling biomacromolecule interactions-NMR and optical spectroscopy studies on ligand binding to DNA and lysozyme
Abstract : Studies on intercalation of bulky binuclear ruthenium compounds into DNA have attracted attention due to their slow dissociation rate and sequence selectivity. Previous results showed that dumb-bell shaped molecules of the type [μ-(bidppz)(L)4Ru2]4+, L=phenanthroline or bipyridine, bind rapidly on the surface of DNA prior to intercalation. READ MORE

4. Structural Transitions in Helical Peptides : The Influence of Water – Implications for Molecular Recognition and Protein Folding
Abstract : Fluctuations in protein structure are vital to function. This contrasts the dominating structure-function paradigm, which connects the well-defined three-dimensional protein structure to its function. However, catalysis is observed in disordered enzymes, which lack a defined structure. READ MORE

5. Chemical Processes at the Water-Manganite (γ-MnOOH) Interface
Abstract : The chemistry of mineral surfaces is of great importance in many different areas including natural processes occurring in oceans, rivers, lakes and soils. Manganese (hydr)oxides are one important group to these natural processes, and the thermodynamically most stable trivalent manganese (hydr)oxide, manganit (γ-MnOOH), is studied in this thesis.
