Homology model of RepA homodimer (shown in blue and gold) based on the RepE structure (shown in gray). (A) Full protein dimer. (B) Zoomed in view of N99 and R46 residues, the two most commonly isolated RepA mutants. (C) Potential electrostatic interaction between residues E93 and K102. (D) Potential electrostatic interaction between residues E115 and R43.
