Excision of Oxidatively Generated Guanine Lesions by Competing Base and Nucleotide Excision Repair Mechanisms in Human Cells

The interchange between different repair mechanisms in human cells has long been a subject of interest. Here, we provide a direct demonstration that the oxidatively generated guanine lesions spiroiminodihydantoin (Sp) and 5-guanidinohydantoin (Gh) embedded in double-stranded DNA, are substrates of b...
