Protein alignment of p42d RepC from R. etli CFN42 and pSymA RepC from S. meliloti 1021 and where identical amino acid residues are marked in red. The secondary structures of these proteins are also shown. Coiled regions are marked with C; helical regions are marked with boxed H letters; and with letter E, the stranded regions. Arrows with an associated numbers indicates the positions where the genes were swap, in the hybrid genes (see table 1).
