Abstract:
The widely conserved bacterial transcription repair coupling factor (TRCF) is a large, multidomain, superfamily 2 ATPase. It couples nucleotide excision repair with transcription by dislodging inactive RNA polymerase molecules stalled at template DNA lesions and increasing the rate at which the Uvr(A)BC excinuclease acts at these sites. The recent elucidation of X-ray crystal structures of Escherichia coli TRCF revealed its architectural details, and will enable the design of more incisive experiments addressing how TRCF translocates on double-stranded DNA, destabilizes the RNA polymerase ternary elongation complex and recruits the Uvr(A)BC system.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
