The sequences encoding the QUAD1 RNAs were initially identified as four repeats in Escherichia coli. These repeats, herein renamed SIB, are conserved in closely related bacteria, although the number of repeats varies. All five Sib RNAs in E. coli MG1655 are expressed, and no phenotype was observed for a five-sib deletion strain. However, a phenotype(More)
The assembly of DNA into chromatin in eukaryotic cells affects all DNA-related cellular activities, such as replication, transcription, recombination, and repair. Rearrangement of chromatin structure during nucleotide excision repair (NER) was discovered more than 2 decades ago. However, the molecular basis of chromatin dynamics during NER remains(More)
Bulky DNA damage is corrected by the nucleotide excision repair (NER) pathway. Although the core biochemical mechanism of NER is understood, details including lesion recognition and repair in the context of chromatin remain to be elucidated. As more data become available, the complexity of lesion recognition in chromatin is becoming clear. This review will(More)
How DNA repair proteins interact with the dynamic structure of chromatin is an emerging question. Chromatin structure impedes the access of repair proteins to sites of DNA damage. Several recent studies have implicated chromatin remodeling complexes in DNA repair. In this report we summarize the methods we used to investigate chromatin remodeling during(More)
