Extended Data Fig. 1: Cryo-EM structure determination of the nucleotide-free apo condensin complex.
From: Cryo-EM structures of holo condensin reveal a subunit flip-flop mechanism
a, Representative micrographs of nucleotide-free (apo) condensin tetramer (Smc2–Smc4–Brn1–Ycs4, left) and pentamer (Smc2–Smc4–Brn1–Ycs4–Ycg1, right). b, Workflow of initial data processing. Representative 2D classes are shown for the tetramer and pentamer data sets. Density map, angular distribution plot and FSC curves of the overall complexes in c, the non-engaged and d, the bridged state.
