Robustness in Protein Folding Revealed by Thermodynamics Calculations

Qiang Shao、Weiliang Zhu、Yi Qin Gao2012-11-06The Journal of Physical Chemistry B

Long-range intraprotein interactions play important roles in protein folding. In the present study, we use two variants of the B domain of protein A (BdpA F14W/G30A and BdpA_ds) and two variants of the Trp cage (TC5b_P1 and TC5b_P2) as models to investigate how long-range hydrophobic interactions affect protein tertia…

Abstract. To improve the model prediction for the formation of H2SO4 and methanesulfonic acid (MSA), aerosol-phase reactions of gaseous dimethyl sulfide (DMS) oxidation products [e.g., dimethyl sulfoxide (DMSO)] in aerosol have been included in the DMS kinetic model with the recently reported gas-phase reactions and t…

Origin of rebounds with a restitution coefficient larger than unity in nanocluster collisions

Hiroto Kuninaka、Hisao Hayakawa2012-11-06Physical Review E

We numerically investigate the mechanism of super rebounds (rebounds in which the restitution coefficient is larger than unity) for head-on collisions between nanoclusters. It is confirmed that the temperature and the entropy of the nanocluters decrease after the super rebounds by our molecular dynamics simulations. I…
