Flat projection of the three-dimensional structure of the BRC repeat in the RAD51A protein. The position corresponding to the polymorphic residue 110 in maize RAD51A2 is marked with an arrow. This amino acid is located at the base of a small loop on the protein surface that is adjacent to the Mg2+-binding pocket in the ATPase domain
