Figure 4. Models of nucleosome sliding via twist defects.

Figure 4.

(a) Overview of remodeler-catalyzed DNA motions, showing that DNA first shifts onto the nucleosome from the entry side, is transiently absorbed on the nucleosome after being expelled from SHL2, and then shifts off the exit side.

(b) Possible pathways for how remodeler ATPases stimulate 1 bp shifts of DNA around the nucleosome.
