Statistical Mechanics of Membrane Protein Conformation: A Homopolymer Model
Pyeong Jun Park, W. Sung
The conformation and the phase diagram of a membrane protein are investigated via grand canonical ensemble approach using a homopolymer model. We discuss the nature and pathway of…
Polymer translocation induced by adsorption
Pyeong Jun Park, Wokyung Sung
We study the translocation of a flexible polymer through a pore in a membrane induced by its adsorption on \trans side of the membrane. When temperature is higher than , t…
Polymer Release out of a Spherical Vesicle through a Pore
Pyeong Jun Park, Wokyung Sung
Translocation of a polymer out of curved surface or membrane is studied via mean first passage time approach. Membrane curvature gives rise to a constraint on polymer conformation,…
Polymer Translocation througha Pore in a Membrane
W. Sung, P. J. Park
We construct a new statistical physical model of polymer translocation through a pore in a membrane treated as the diffusion process across a free energy barrier. We determine the…
