CC   -!- FUNCTION: Endonuclease that specifically degrades the RNA of RNA-DNA
CC       hybrids. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.; EC=3.1.26.4;
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
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:0000250};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the RNase HII family. {ECO:0000305}.
