==Overview==
[[Category: Quigley GJ]]
Ditercalinium is a synthetic anticancer drug that binds to DNA by bis-intercalation and activates DNA repair processes. In prokaryotes, noncovalent DNA-ditercalinium complexes are incorrectly recognized by the uvrABC repair system as covalent lesions on DNA. In eukaryotes, mitochondrial DNA is degraded by excess and futile DNA repair. Using x-ray crystallography, we have determined, to 1.7 A resolution, the three-dimensional structure of a complex of ditercalinium bound to the double-stranded DNA fragment [d(CGCG)]2. The DNA in the complex with ditercalinium is kinked (by 15 degrees) and severely unwound (by 36 degrees) with exceptionally wide major and minor grooves. Recognition of the DNA-ditercalinium complex by uvrABC in prokaryotes, and by mitochondrial DNA repair systems in eukaryotes, might be related to drug-induced distortion of the DNA helix.
