CC -!- FUNCTION: Endonuclease that specifically degrades the RNA of RNA-DNA
CC hybrids. {ECO:0000256|HAMAP-Rule:MF_00042}.
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_00042};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00042};
CC Note=Binds 1 Mg(2+) ion per subunit. May bind a second metal ion at a
CC regulatory site, or after substrate binding. {ECO:0000256|HAMAP-
CC Rule:MF_00042};
CC -!- SUBUNIT: Monomer. {ECO:0000256|ARBA:ARBA00011245, ECO:0000256|HAMAP-
CC Rule:MF_00042}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00042}.
CC -!- SIMILARITY: Belongs to the RNase H family.
CC {ECO:0000256|ARBA:ARBA00005300, ECO:0000256|HAMAP-Rule:MF_00042}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00042}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
