FIG. 5.
Cleavage of DNA duplexes containing a single 8-oxoG mismatched with one of the four bases C (■), T (▾), G (▴), and A (•). The various duplexes (100 fmol) were incubated with increasing amounts of proteins standardized as Fapy-DNA glycosylase activity of fraction V (A) and fraction VI (B) for 10 min at 32°C.
