Analyzing ion distributions around DNA

John Maddocks, Marco Pasi

We present a new method for analyzing ion, or molecule, distributions around helical nucleic acids and illustrate the approach by analyzing data derived from molecular dynamics simulations. The analysis is based on the use of curvilinear helicoidal coordin ...

Free-energy landscape of protein oligomerization from atomistic simulations

Alessandro Barducci

In the realm of protein-protein interactions, the assembly process of homooligomers plays a fundamental role because the majority of proteins fall into this category. A comprehensive understanding of this multistep process requires the characterization of ...

Entropy in the Coil-to-Globule Transition of Macromolecules : Insights from Simple Models

Carlo Maffi

The coil to globule transition is a fundamental phenomenon in the physics of macro-molecules by reason of the multiplicity of arrangements of their conformation. Such conformational freedom is the main source of entropy in the molecule and is the main oppo ...

Explaining the length threshold of polyglutamine aggregation

Paolo De Los Rios, Marc Hafner

The existence of a length threshold, of about 35 residues, above which polyglutamine repeats can give rise to aggregation and to pathologies, is one of the hallmarks of polyglutamine neurodegenerative diseases such as Huntington's disease. The reason why s ...
