title: Translesion synthesis by human DNA polymerase eta across oxidative products of guanine.
abstract: Guanine is the most oxidizable base among natural bases. 8-Oxoguanine (8-oxoG) is the typical oxidative product, but the amount of 8-oxoG does not directly reflect the strength of oxidative stress. Imidazolone, oxazolone and guanidinohydantoin are oxidative products of guanine and 8-oxoG. Here, we investigated enzymatic reactions with human DNA polymerase eta on these lesions.
