Significance of DNA polymerase I in in vivo processing of clustered DNA damage

Abstract:

We examined the biological consequences of bi-stranded clustered damage sites, consisting of a combination of DNA lesions, such as a 1-nucleotide gap (GAP), an apurinic/apyrimidinic (AP) site, and an 8-oxo-7,8-dihydroguanine (8-oxoG), using a bacterial plasmid-based assay. Following transformation with the plasmid containing bi-stranded clustered damage sites into the wild type strain of Escherichia coli, transformation frequencies were significantly lower for the bi-stranded clustered GAP/AP...
