THE COMPLEX LIES ON A CRYSTALLOGRAPHIC TWO-FOLD AXIS, AND ONLY ONE MONOMER-DNA HALF-SITE CONSTITUTES THE ASYMMETRIC UNIT. THE COORDINATES COMPRISE ONE REPRESSOR MONOMER AND ONE DNA STRAND FOR THE ENTIRE SITE. THE FULL COMPLEX CAN BE CONSTRUCTED BY GENERATING THE SECOND HALF USING THE CRYSTALLOGRAPHIC SYMMETRY OPERATION (X, -Y, -Z).
