Heberle,Stefania Perticaroli,Stefania Perticaroli,Mikhail Feygenson,Takeshi Egami,Robert F. Standaert,Robert F. Standaert,Jeremy C. Smith,Jeremy C. Smith,Dean A. A. Myles,Michael Ohl,John Katsaras,John Katsaras,John Katsaras +22 more
TL;DR: The results inform a number of theoretical models of domain/raft formation and highlight the fact that mismatches in bending modulus must be accounted for when explaining the emergence of lateral heterogeneities in lipid systems and biological membranes.
Journal ArticleDOI
Structure and Hydration of Highly-Branched, Monodisperse Phytoglycogen Nanoparticles
Jonathan D. Nickels,Jonathan D. Nickels,John Atkinson,Erzsebet Papp-Szabo,Christopher B. Stanley,Souleymane Diallo,Stefania Perticaroli,Benjamin Baylis,Perry Mahon,Georg Ehlers,John Katsaras,John Katsaras,John Dutcher +12 more
TL;DR: In this article, the structure and hydration of aqueous dispersions of phytoglycogen nanoparticles using neutron scattering was characterized. But the authors did not consider the effect of the number of water molecules in the dispersions.
Journal ArticleDOI
Description of Hydration Water in Protein (Green Fluorescent Protein) Solution
Stefania Perticaroli,Georg Ehlers,Georg Ehlers,Christopher B. Stanley,Christopher B. Stanley,Eugene Mamontov,Eugene Mamontov,Hugh O'Neill,Hugh O'Neill,Qiu Zhang,Qiu Zhang,Xiaolin Cheng,Xiaolin Cheng,Dean A. A. Myles,Dean A. A. Myles,John Katsaras,John Katsaras,Jonathan D. Nickels,Jonathan D. Nickels +18 more
TL;DR: An experimental description of the dynamical perturbation of hydration water around green fluorescent protein in solution helps clarify the seemingly conflicting range of values reported for hydrationWater retardation as a logical consequence of the different length scales probed by the analytical techniques used.
Journal ArticleDOI
Secondary structure and rigidity in model proteins
Stefania Perticaroli,Stefania Perticaroli,Jonathan D. Nickels,Georg Ehlers,Hugh O'Neill,Hugh O'Neill,Qui Zhang,Qui Zhang,Alexei P. Sokolov,Alexei P. Sokolov +9 more
TL;DR: The experimental results show that in these model proteins, the β motif is a stiffer structural unit than the α-helix in both dry and hydrated states, and analysis suggests an intimate connection of dynamics and rigidity with the protein secondary structure.
Journal ArticleDOI
Broadband depolarized light scattering study of diluted protein aqueous solutions.
Stefania Perticaroli,Lucia Comez,Marco Paolantoni,Paola Sassi,Laura Lupi,Daniele Fioretto,Alessandro Paciaroni,Assunta Morresi +7 more
TL;DR: A broadband depolarized light scattering study on diluted lysozyme aqueous solutions shows that the proposed approach represents a suitable tool for investigating the hydration dynamics of protein-water solutions and evidences the existence of two distinct relaxational processes at picosecond time scales.
