Depurination of N7-methylguanine by DNA glycosylase AlkD is dependent on the DNA backbone

DNA glycosylase AlkD excises N7-methylguanine (7mG) by a unique but unknown mechanism, in which the damaged nucleotide is positioned away from the protein and the phosphate backbone distorted. Here, we show by methylphosphonate substitution that a phosphate proximal to the lesion has a significant e...
