Fig. 3: Structural comparison of AtDDM1-bound and AtDDM1-free nucleosomes.
From: Molecular and structural basis of the chromatin remodeling activity by Arabidopsis DDM1
Cryo-EM structures of the AtDDM1-AtH2A.W nucleosome complex (a) and the AtH2A.W nucleosome (b). Structures of nucleosomal DNA are compared at SHL −7 to 0 (middle) and SHL 0 to +7 (right). Blue arrowheads indicate the dyad axis. Black arrowheads indicate the terminal DNA detected by cryo-EM density maps. Dashed red circles indicate the AtH2A.W docking domain and the H3 αN helix disordered in the AtDDM1-AtH2A.W nucleosome complex.
