中文摘要 | In eukaryote nucleosome, DNA wraps around a historic octamer in a left-handed way. We study the process of chirality formation of nucleosome with Brownian dynamics simulation. We model the historic octamer with a quantitatively adjustable chirality: left-handed, right-handed or non-chiral, and simulate the dynamical wrapping process of a DNA molecule on it. We find that the chirality of a nucleosome formed is strongly dependent on that of the historic octamer, and different chiralities of the histone octamer induce its different rotation directions in the wrapping process of DNA. In addition, a very weak chirality of the historic octamer is quite enough for sustaining the correct chirality of the nucleosome formed. We also show that the chirality of a nucleosome may be broken at elevated temperature. © 2005 Elsevier Ltd. All rights reserved. |
