Non-B DNA structures affect DNA repair efficiency and accuracy. NonB
DNA conformations alter the structural features of B-DNA helices
and thus the accessibility of DNA damaging agents and DNA repair
protein to the damaged sites. The binding affinity and repair effi-
ciency of hOGG1 protein on 8-oxoG in a hairpin structure was
significantly reduced compared to 8-oxoG in B-DNA [133].
