Visualizing Chiral Interactions in Carbohydrates Adsorbed on Au(111) by High-Resolution STM Imaging
Klaus Kern, Uta Schlickum, Stephan Rauschenbach
Carbohydrates are the most abundant organic material on Earth and the structural "material of choice" in many living systems. Nevertheless, design and engineering of synthetic carbohydrate materials presently lag behind that for protein and nucleic acids. ...
WILEY-V C H VERLAG GMBH2023cgNA+: A sequence-dependent coarse-grain model of double-stranded nucleic acids
DNA mechanics plays a crucial role in many biological processes, including nucleosome positioning and protein-DNA interactions. It is believed that nature employs epigenetic modifications in DNA to further regulate gene expression. Moreover, double-strande ...
EPFL2023Indication of 310-Helix Structure in Gas-Phase Neutral Pentaalanine
We investigate the gas-phase structure of the neutral pentaalanine peptide. The IR spectrum in the 340-1820 cm-1 frequency range is obtained by employing supersonic jet cooling, infrared multiphoton dissociation, and vacuum-ultraviolet action spectroscopy. ...
AMER CHEMICAL SOC2023Equilibrium and non-equilibrium furanose selection in the ribose isomerisation network
Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang, Francesco Piazza
The exclusive presence of beta -D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium. However, a precise characterisation of the relative furanose/pyranose fra ...
NATURE RESEARCH2021IR-induced conformational isomerization of a helical peptide in a cold ion trap
Thomas Rizzo, Aleksandra Zabuga, Annette Svendsen, Caroline Seaiby
In this work we use laser-induced population transfer techniques to study the conformational isomerization of a helical peptide, Ac-Phe-(Ala)5-LysH+, in a cold ion trap. In one scheme, called IR-UV hole-filling spectroscopy, a single conformation is select ...
