  • PubMed Abstract: 

    One of the primary pathways for removal of DNA damage is nucleotide excision repair (NER). In bacteria, the UvrA protein is the component of NER that locates the lesion. A notable feature of NER is its ability to act on many DNA modifications that vary in chemical structure. So far, the mechanism underlying this broad specificity has been unclear. Here, we report the first crystal structure of a UvrA protein in complex with a chemically modified oligonucleotide. The structure shows that the UvrA dimer does not contact the site of lesion directly, but rather binds the DNA regions on both sides of the modification. The DNA region harboring the modification is deformed, with the double helix bent and unwound. UvrA uses damage-induced deformations of the DNA and a less rigid structure of the modified double helix for indirect readout of the lesion.
