3I0W, 3I0X - PubMed Abstract: 
7,8-Dihydro-8-oxoguanine (8-oxoG) is the major oxidative product of guanine and the most prevalent base lesion observed in DNA molecules. Because 8-oxoG has the capability to form a Hoogsteen pair with adenine (8-oxoG:A) in addition to a normal Watson-Crick pair with cytosine (8-oxoG:C), this lesion can lead to a G:C-->T:A transversion after replication ...
