CC -!- FUNCTION: Involved in base excision repair of DNA damaged by oxidation
CC or by mutagenic agents. Acts as DNA glycosylase that recognizes and
CC removes damaged bases. Has a preference for oxidized purines, such as
CC 7,8-dihydro-8-oxoguanine (8-oxoG). Has AP (apurinic/apyrimidinic) lyase
CC activity and introduces nicks in the DNA strand. Cleaves the DNA
CC backbone by beta-delta elimination to generate a single-strand break at
CC the site of the removed base with both 3'- and 5'-phosphates.
CC {ECO:0000255|HAMAP-Rule:MF_00103}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of DNA containing ring-opened 7-methylguanine
CC residues, releasing 2,6-diamino-4-hydroxy-5-(N-
CC methyl)formamidopyrimidine.; EC=3.2.2.23;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00103};
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 2'-deoxyribonucleoside-DNA + H(+); Xref=Rhea:RHEA:66592, Rhea:RHEA-
