From their electron density, it appears the translated DNA sequence is correct ; 2) It is possible residue 119 could be a Tyr rather than Asp based on some electron density evidence.

The DNA axis is in parallel with the crystallographic z-axis (a 4-fold screw axis). To have a complete DNA molecule, we indexed the diffraction data in a lower symmetry space group P21. The two protein molecules along the DNA axis were constrained during the refinement by non-crystallographic 4-fold screw symmetry.
