CC -!- FUNCTION: DNA repair enzyme that is part of the base excision repair
CC (BER) pathway; protects from oxidative damage by removing the major
CC product of DNA oxidation, 8-oxoguanine (GO), from single- and double-
CC stranded DNA substrates. {ECO:0000255|HAMAP-Rule:MF_01168}.
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-
CC COMP:13180, Rhea:RHEA-COMP:16897, Rhea:RHEA-COMP:17067,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:136412, ChEBI:CHEBI:157695,
CC ChEBI:CHEBI:167181; EC=4.2.99.18; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01168};
CC -!- DOMAIN: Contains two alpha-helical subdomains, with the 8-oxoguanine
CC binding site located in a cleft at their interface. Contains a helix-
CC hairpin-helix (HhH) structural motif and a Gly/Pro-rich sequence
CC followed by a conserved Asp (HhH-GPD motif).
CC -!- SIMILARITY: Belongs to the archaeal N-glycosylase/DNA lyase (AGOG)
CC family. {ECO:0000255|HAMAP-Rule:MF_01168}.
