RT Natronomonas pharaonis.";
RL Genome Res. 15:1336-1343(2005).
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}.
