CC   -!- FUNCTION: Endonuclease that specifically degrades the RNA of RNA-DNA
CC       hybrids. {ECO:0000255|HAMAP-Rule:MF_00052}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.; EC=3.1.26.4;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00052};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00052};
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00052};
CC       Note=Manganese or magnesium. Binds 1 divalent metal ion per monomer in
CC       the absence of substrate. May bind a second metal ion after substrate
CC       binding. {ECO:0000255|HAMAP-Rule:MF_00052};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00052}.
