Fast, Accurate, and System-Specific Variable-Resolution Modeling of Proteins
R. Fiorentini, T. Tarenzi, R. Potestio, Fast, Accurate, and System-Specific Variable-Resolution Modeling of Proteins, J. Chem. Inf. Model. (2023) In recent years, a few multiple-resolution modeling strategies have been proposed, in which functionally relevant parts of a biomolecule are described with atomistic resolution, with the remainder of the system being concurrently treated using a coarse-grained …

Making sense of complex systems through resolution, relevance, and mapping entropy
R. Holtzman, M. Giulini, R. Potestio, Making sense of complex systems through resolution, relevance, and mapping entropy, Phys. Rev. E (2022) Complex systems are characterized by a tight, nontrivial interplay of their constituents, which gives rise to a multiscale spectrum of emergent properties. In this scenario, it is practically and conceptually difficult to identify those degrees …

Information-theoretical measures identify accurate low-resolution representations of protein configurational space
M. Mele, R. Covino, R. Potestio, Information-theoretical measures identify accurate low-resolution representations of protein configurational space, Soft Matter (2022) The steadily growing computational power employed to perform molecular dynamics simulations of biological macromolecules represents at the same time an immense opportunity and a formidable challenge. In fact, large amounts of data are produced, from which useful, …

Dynamic and facilitated binding of topoisomerase accelerates topological relaxation
D. Michieletto, Y. A. G. Fosado, E. Melas, M. Baiesi, L. Tubiana, E. Orlandini, Dynamic and facilitated binding of topoisomerase accelerates topological relaxation, Nucleic Acids Research (2022) How type 2 Topoisomerase (TopoII) proteins relax and simplify the topology of DNA molecules is one of the most intriguing open questions in genome and DNA biophysics. Most …

Stochastic dynamics and bound states of heavy impurities in a Fermi bath
M. Sighinolfi, D. De Boni, A. Roggero, G. Garberoglio, P. Faccioli, and A. Recati, Stochastic dynamics and bound states of heavy impurities in a Fermi bath, Phys Rev A (2022) We investigate the dynamics of heavy impurities embedded in an ultracold Fermi gas by using a generalized Langevin equation. The latter—derived by means of influence …

Membrane binding of pore-forming γ-hemolysin components studied at different lipid compositions
T. Tarenzi, G. Lattanzi. R. Potestio, Membrane binding of pore-forming γ-hemolysin components studied at different lipid compositions, BBA Biomembranes (2022) Methicillin-resistant Staphylococcus aureus is among those pathogens currently posing the highest threat to public health. Its host immune evasion strategy is mediated by pore-forming toxins (PFTs), among which the bi-component γ-hemolysin is one of the most common. The complexity …
