Exocyclic amino groups of flanking guanines govern sequence-dependent adduct conformations and local structural distortions for minor groove-aligned benzo[a]pyrenyl-guanine lesions in a GG mutation hotspot context

The environmental carcinogen benzo[a]pyrene (BP) is metabolized to reactive diol epoxides that bind to cellular DNA by predominantly forming N(2)-guanine adducts (G*). Mutation hotspots for these adducts are frequently found in 5′- ··· GG ··· dinucleotide sequences, but their origins are poorly unde...
