Using electron microscopy, we have reconstructed five different states of RecA-DNA filaments. The C-terminal lobe of the RecA protein is modulated by the state of the distantly bound nucleotide, and this allosteric coupling can explain how mutations and truncations of this C-terminal lobe enhance RecA's activity. A model generated from these reconstructions shows that the nucleotide binding core is substantially rotated from its position in the RecA crystal filament, resulting in ATP binding between subunits. This simple rotation can explain the large cooperativity in ATP hydrolysis observed for RecA-DNA filaments.
