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 ...
Despite of considerable progress in the research at the interface of Chemistry, Biology and Medicine, neurodegenerative diseases affect more and more seriously our ageing population and remain a real therapeutic challenge for researcher. Nevertheless, adva ...
The mechanism of chiral induction in an optically pure 1,3-diethynylallene, from the central chiral allene moiety into directly adjacent TCBD chromophores, was confirmed and clarified. Only one low-energy conformer is found in calcns. of the potential ener ...
We study the behavior of single-stranded DNA (ssDNA) in the presence of well-known drugs with either an intercalating binding mode, such as daunorubicin, actinomycin D, and chloroquine, or a minor groove binding mode, such as netropsin and berenil, by atom ...
The length of the Yersinia injectisome needle is determined by the protein YscP, which could act as a molecular ruler. The analysis of the correlation between the size of YscP and the needle length in seven wild-type strains of Yersinia enterocolitica rein ...
Conformational transitions have found broad interest due to their impact on protein misfolding and self-assembly as key events leading to the development of neurodegenerative diseases. However, investigation of these dynamic events has been limited so far ...
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 ...
Aspects of conformational transitions, folding, and misfolding of peptides and proteins have recently taken center stage in various domains at the interface of chemistry, biology, and medicine because of their impact on protein misfolding diseases. Due to ...
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 ...
Intramol. O,N-acyl migration reactions were used as structural switch (S-elements) from a depsipeptide bond contg., unfolded state (Soff) to an all-amide, native states (Son). Chem. or enzymically triggered acyl migrations allowed for the controlled induct ...
