Molecular Effects of Concentrated Solutes on Protein Hydration, Dynamics, and Electrostatics

Matteo Dal Peraro, Enrico Spiga, Luciano Andres Abriata

Most studies of protein structure and function are performed in dilute conditions, but proteins typically experience high solute concentrations in their physiological scenarios and biotechnological applications. High solute concentrations have well-known e ...

Dissecting the Effects of Concentrated Carbohydrate Solutions on Protein Diffusion, Hydration, and Internal Dynamics

Francesco Piazza, Matteo Dal Peraro, Enrico Spiga, Luciano Andres Abriata

We present herein a thorough description of the effects of high glucose concentrations on the diffusion, hydration and internal dynamics of ubiquitin, as predicted from extensive molecular dynamics simulations on several systems described at fully atomisti ...

New Strategies for Integrative Dynamic Modeling of Macromolecular Assembly

Matteo Thomas Degiacomi, Matteo Dal Peraro, Enrico Spiga

Data reporting on structure and dynamics of cellular constituents are growing with increasing pace enabling, as never before, the understanding of fine mechanistic aspects of biological systems and providing the possibility to affect them in controlled way ...

Multiscale simulations of protein dynamics

Enrico Spiga

Characteristic timescales associated with the function of biomolecules, like proteins, range from femtoseconds up to minutes, whereas their corresponding spatial extent ranges from few ̊A to μm when associating in large macromolecular complexes. Moreover, ...

Electrostatic-Consistent Coarse-Grained Potentials for Molecular Simulations of Proteins

Matteo Thomas Degiacomi, Michele Cascella, Matteo Dal Peraro, Enrico Spiga, Davide Alemani

We present a new generation of coarse-grained (CG) potentials that account for a simplified electrostatic description of soluble proteins. The treatment of permanent electrostatic dipoles of the backbone and polar side-chains allows to simulate proteins, p ...

All-atom simulations of crowding effects on ubiquitin dynamics

Matteo Dal Peraro, Enrico Spiga, Luciano Andres Abriata

It is well-known that crowded environments affect the stability of proteins, with strong biological and biotechnological implications; however, beyond this, crowding is also expected to affect the dynamic properties of proteins, an idea that is hard to pro ...
