Chromatin remodeling

Chromatin remodeling is the enzyme-assisted movement of nucleosomes on DNA.

This is performed by chromatin remodeling complexes like SWI/SNF (human, yeast), RSC (yeast) and Imitation SWI complexes (fly).

At the core of a chromatin remodeling complexes is an ATPase capable of DNA translocation.

By moving nucleosomes, proteins like transcription factors can get access to DNA that was previously unavailable, wrapped around nucleosome cores.
