CC   -!- FUNCTION: Catalyzes the excision of an oxidatively damaged form of
CC       guanine (7,8-dihydro-8-oxoguanine = 8-oxoG) from DNA. Also cleaves the
CC       DNA backbone at apurinic/apyrimidinic sites (AP sites).
CC       {ECO:0000255|HAMAP-Rule:MF_00241}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2'-deoxyribonucleotide-(2'-deoxyribose 5'-phosphate)-2'-
CC         deoxyribonucleotide-DNA = a 3'-end 2'-deoxyribonucleotide-(2,3-
CC         dehydro-2,3-deoxyribose 5'-phosphate)-DNA + a 5'-end 5'-monophospho-

CC         Rule:MF_00241};
CC   -!- SIMILARITY: Belongs to the type-2 OGG1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00241, ECO:0000305}.
