1. Biophysical studies of cell-penetrating peptides and of the RNR inhibitor Sml1
Abstract : Several short peptides, so called cell-penetrating peptides, have the capability to transport large hydrophilic cargos through the cell membrane. The objective is to use these peptides as drug carriers and thereby enhance the uptake of drugs into cells.Three different cell-penetrating peptides are characterized in this thesis. READ MORE

2. Structure and Dynamics of Membrane Associated Peptides
Abstract : The peptide-membrane interaction is a key element for many biological functions, from cell signaling to cell internalization. In this thesis the peptide-membrane interaction of six different peptides have been studied with respect to their structure, membrane location and dynamics with spectroscopic methods. READ MORE

4. Spectroscopic studies of dynorphin neuropeptides and the amyloid beta-peptide : The consequences of biomembrane interactions
Abstract : Dynorphin A, dynorphin B and big dynorphin are endogenous opioid neuropeptides. They play an important role in a wide variety of physiological functions such as regulation of pain processing and memory acquisition. Such actions are generally mediated through the κ-receptors. READ MORE

5. Experimental studies of proton translocation reactions in biological systems : Electrogenic events in heme-copper oxidases
Abstract : Terminal heme-copper oxidases (HCuOs) are transmembrane proteins that catalyze the final step in the respiratory chain - the reduction of O2 to H2O, coupled to energy conservation by generation of an electrochemical proton gradient. The most extensively investigated of the HCuOs are the aa3-type oxidases, to which cytochrome c oxidase (CytcO) belongs, which uses energy released in the O2-reduction for proton pumping. READ MORE
