The Chromodomains Reshape CHD1 in chromatin regulate access to DNA-ATPase motor Glenn Hauk, Jeffrey N. McKnight, Ilana M. Nodelman, and Gregory D. Bowman1 TC Jenkins Department of Biophysics, Johns Hopkins University in Baltimore, Maryland 21 218 2685 are, USA Abstract chromatin remodeling machines, the ATP-engine, mounted slide, and to remove DNA from nucleosomes, However, as the ATPase motors is regulated remodelers poorly understood.
Here we show that the unity of the dual Chromodom block Ne DNA binding and activation of the motor remodelers CHD1 ATPase in the absence of nucleosome substrates. The crystal structure shows a propeller CHD1 chromodomains S range Acid can pack against a surface Chemical DNA-binding ATPase motor. The interruption of the interface Chromodom Ne ATPase prevents discrimination between the nucleosomes and naked DNA and reduces dependence Dependence of the histone H4 tail for nucleosome sliding. We suggest that CHD1 chromodomains can distinguish between nucleosomes and naked DNA by physically access door motor ATPase, and we assume that ATPase motors can k One Similar strategy to distinguish between using DNA substrates. Chromatin-Pr Presentation, the physical packaging of eukaryotic chromosomes, play a role The central in the regulation of gene silencing and expression patterns genome.
