Molecular dynamics (MD) simulations have increasingly contributed to the understanding of biomolecular processes, allowing for predictions of thermodynamic and structural properties. Unfortunately, the holy grail of protein structure prediction was soon fo ...
The rapid growing number of patients diagnosed with a neurodegenerative disease and more particularly with Alzheimer's disease (AD) has stimulated intensive research in determining and understanding biological phenomena causing such devastating diseases an ...
Peptide based and peptide hybrid materials represent two interesting and challenging classes of biomaterials. Both classes consist of and contain, respectively, one or more polypeptide blocks, endowing the resulting polymers with enhanced self-assembly pro ...
The formation of supramolecular structures is a central issue in bio- and nanotechnology and therein plays an important role for many novel developments such as biocompatible materials for integrating living cells or coating for implantable sensing devices ...
The aggregation of proteins into amyloid fibrils is associated with several neurodegenerative diseases. In Parkinson's disease it is believed that the aggregation of a-synuclein (alpha-syn) from monomers by intermediates into amyloid fibrils is the toxic d ...

The study of conformational transitions of peptides has obtained considerable attention recently because of their importance as a mol. key event in a variety of degenerative diseases. However, the study of peptide self-assembly into beta-sheets and amyloid ...
Because of the importance of helices in the secondary structure of proteins, we have undertaken a study of their spectroscopy, fragmentation patterns and conformations in the gas phase. In this work, we describe the effects of substitution at the N-terminu ...
The conformational search for favorable intramolecular interactions during protein folding is limited by intrachain diffusion processes. Recent studies on the dynamics of loop formation in unfolded polypeptide chains have focused on loops involving residue ...
Aggregation and fibril formation of amyloid-beta (Abeta) peptides Abeta40 and Abeta42 are central events in the pathogenesis of Alzheimer disease. Previous studies have established the ratio of Abeta40 to Abeta42 as an important factor in determining the f ...

Reversal of amyloid formation through a controlled induced transformation from beta-sheet to sol. alpha-helix structures through the use of a switch element S could have an important consequences understanding the mechanisms of amyloid formation and cleara ...
