abstract：:Nucleotide excision DNA repair is mechanistically conserved across all kingdoms of life. In prokaryotes, this multi-enzyme process requires six proteins: UvrA-D, DNA polymerase I and DNA ligase. To examine how UvrC locates the UvrB-DNA pre-incision complex at a site of damage, we have labeled UvrB and UvrC with differ...
