FIGURE 1. Core properties of the nucleosome.

FIGURE 1

A. Nucleosome core particle with the surface of the histone octamer colored according to the gradient specified below. The unit kT/e refers to the energy associated with placing a unit charge at a specific location. B. Ribbon diagram of one pseudosymmetrical half of the nucleosome. Locations of nucleosomal DNA are specified according to their SuperHelical Location (SHL) with each location being 10 bp from the dyad axis of symmetry. C. Dynamic states of a nucleosome in solution. Nucleosomes exist in equilibrium between many possible states. Transition between states may involve conformational changes in the histone octamer (e.g. during DNA breathing).
