Cage rattling does not correlate with the local geometry in molecular liquids

D. Leporini Dipartimento di Fisica “Enrico Fermi”, Università di Pisa, Largo B.Pontecorvo 3, I-56127 Pisa, Italy and IPCF-CNR, UOS Pisa, Italy (Dated: May 4, 2016) Abstract Molecular-dynamics simulations of a liquid of short linear molecules have been performed to investigate the correlation between the particle dynamics in the cage of the neighbors and the local geometry. The latter is charact...

Rattling the cage and opening the door.

I share with Poulin-Dubois and with Sabbagh, Koenig and Kuhlmeier the conviction that more research is needed on the mechanisms supporting selective social learning in infants and children. However, my plea is more specific: for research that tests domain-specific hypotheses about mechanism against domain-general hypotheses derived from other fields of cognitive science. Many, but not all, of t...

Rattling the cage: computational models of chaperonin-mediated protein folding.

Chaperonins are known to maintain the stability of the proteome by facilitating the productive folding of numerous misfolded or aggregation-prone proteins and are thus essential for cell viability. Despite their established importance, the mechanism by which chaperonins facilitate protein folding remains unknown. Computer simulation techniques are now being employed to complement experimental o...

Protein dynamics: from rattling in a cage to structural relaxation.

We present an overview of protein dynamics based mostly on results of neutron scattering, dielectric relaxation spectroscopy and molecular dynamics simulations. We identify several major classes of protein motions on the time scale from faster than picoseconds to several microseconds, and discuss the coupling of these processes to solvent dynamics. Our analysis suggests that the microsecond bac...
