CC -!- FUNCTION: Endonuclease that specifically degrades the RNA of RNA-DNA
CC hybrids. {ECO:0000256|RuleBase:RU003515}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.; EC=3.1.26.4;
CC Evidence={ECO:0000256|ARBA:ARBA00000077, ECO:0000256|PROSITE-
CC ProRule:PRU01319, ECO:0000256|RuleBase:RU003515};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|PROSITE-ProRule:PRU01319};
