Chromatin remodelers are ATP-dependent machines responsible for directionally shifting nucleosomes along DNA. We are interested in defining which elements of the chromodomain helicase DNA-binding protein 1 (Chd1) remodeler are necessary and sufficient for sliding nucleosomes. This work focuses on the polypeptide segment that joins the ATPase motor to the C-terminal DNA-binding domain. We identify amino acid positions outside the ATPase motor that, when altered, dramatically reduce nucleosome sliding ability and yet have only ∼3-fold reduction in ATPase stimulation by nucleosomes. These residues therefore appear to play a role in functionally coupling ATP hydrolysis to nucleosome sliding, and suggest that the ATPase motor requires cooperation with external elements to slide DNA past the histone core.
