Perturbations of Enzymic Initiation of Excision Repair due to Guanine Modification in DNAepair of DNA base alterations is initiated by DNA glycosylases, each of which releases a specific damaged base by cleaving the glycosylic bond linking it to the sugar. The DNA is nicked at the resultant base loss site by an apurinic/apyrimidinic site endonuclease, followed by further endonucleolytic
