EM reconstruction of pB171 ParM filaments. A, the pB171 ParM filament structure, calculated from a subset of filament segments that converged to helical symmetry of 166.1° rotation and 24.2 Å rise per subunit. The map is filtered to 19 Å, the estimated resolution of the reconstruction. Each filament strand is rendered in a different color. B, for comparison, a reconstruction of R1 ParM filaments was calculated, with a refined helical symmetry of 165.4° rotation and 24.5 Å rise per subunit. C, the crystal structure of R1 ParM was manually fit into the EM structure of the pB171 ParM filament, and the fit along a single strand is shown.
