Hydrolysis decreases filament bending. (A) Snapshot of ATP-bound F-MreB, illustrating the three possible intersubunit bending and twisting directions (Supporting Information). Bending occurs primarily around the θ₂ axis (dashed box). (B) Distribution of θ₂ bending angles of ATP- and ADP-bound MreB dimers (solid and dashed, respectively). The histogram of bending from the last 30 ns of each simulation is shown as solid circles and Gaussian fits are shown as continuous curves, with the means and SDs of θ₂ bending given in degrees (Table S3).
