Damage recognition in nucleotide excision DNA repair.

Nucleotide excision repair (NER) is a highly versatile DNA repair process. Its ability to repair a large number of different damages with the same subset of recognition factors requires structural tools for damage recognition that are both broad and very accurate. Over the past few years detailed structural information on damage recognition factors from eukaryotic and prokaryotic NER has emerged. These structures shed light on the toolkit utilized in the damage recognition process and help explain the broad substrate specificity of NER. Copyright Â
