Extended Data Fig. 1: Cryo-EM structure analysis of the Snf2–nucleosome complex in the ADP-bound state.
From: Mechanism of DNA translocation underlying chromatin remodelling by Snf2
a, Representative micrograph of cryo-EM sample. b, Fast Fourier transform (FFT) of image in a with the Thon rings extending to approximately 3.5 Å. c, 2D class averages of characteristic projection views of cryo-EM particles, Snf2–NCP complexes marked with red box were selected for further processing. d, Flow chart of cryo-EM data processing. The linker DNA is visible at low resolution during the 3D classification steps, and becomes invisible at high resolution after auto-refinements. e, The gold-standard FSC curves calculated between two halves of datasets for the Snf2–nucleosome complex in different states. f, Angular distribution of particle projections of the SHL2 complex in the ADP-bound state.
