Comparison of RecA assembly modes.

a Each mode A-I describes one assembly type from ATTRACT docking experiments restricted to the rigid core of the RecA monomer. Last two lines provide corresponding information for the reference crystal forms X and X*; interaction energies Eint for these entries have been calculated between 2REBcore and 3CMWcore respectively, after energy optimization. b Value in Å c Per-interface energy (RT units) d measured with respect to the rigid cores in 2REB and 3CMW, respectively e the per-interface energy of the dimer (A) corresponds to half the value in the ATTRACT output (S2 Protocol, supporting information).
