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}.
CC -!- SIMILARITY: Belongs to the RNase HII family. {ECO:0000255|HAMAP-
CC Rule:MF_00052}.
