RL Submitted (MAR-2013) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Endonuclease that specifically degrades the RNA of RNA-DNA
CC hybrids. {ECO:0000256|ARBA:ARBA00004065, ECO:0000256|HAMAP-
CC Rule:MF_00052, 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|HAMAP-
CC Rule:MF_00052, ECO:0000256|PROSITE-ProRule:PRU01319,
CC 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|HAMAP-Rule:MF_00052,
CC ECO:0000256|PROSITE-ProRule:PRU01319};

CC ECO:0000256|PROSITE-ProRule:PRU01319};
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:0000256|HAMAP-Rule:MF_00052, ECO:0000256|PROSITE-
CC ProRule:PRU01319};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00052}.
CC -!- SIMILARITY: Belongs to the RNase HII family.
CC {ECO:0000256|ARBA:ARBA00007383, ECO:0000256|HAMAP-Rule:MF_00052,
CC ECO:0000256|RuleBase:RU003515}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
