CC -!- FUNCTION: DNA repair enzyme that has both DNA N-glycosylase activity
CC and AP-lyase activity. The DNA N-glycosylase activity releases various
CC damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving
CC an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the
CC phosphodiester bond 3' to the AP site by a beta-elimination, leaving a
CC 3'-terminal unsaturated sugar and a product with a terminal 5'-
CC phosphate. {ECO:0000256|HAMAP-Rule:MF_00942}.
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 -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;

CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000256|HAMAP-Rule:MF_00942};
CC -!- SIMILARITY: Belongs to the Nth/MutY family.
