CC   -!- FUNCTION: DNA repair enzyme involved in the repair of deaminated bases.
CC       Selectively cleaves double-stranded DNA at the second phosphodiester
CC       bond 3' to a deoxyinosine leaving behind the intact lesion on the
CC       nicked DNA. {ECO:0000255|HAMAP-Rule:MF_00801}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage at apurinic or apyrimidinic sites to
CC         products with a 5'-phosphate.; EC=3.1.21.7;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00801};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00801};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00801}.
CC   -!- SIMILARITY: Belongs to the endonuclease V family. {ECO:0000255|HAMAP-
CC       Rule:MF_00801}.
