CC   -!- FUNCTION: Digests double-stranded RNA. Involved in the processing
CC       of primary rRNA transcript to yield the immediate precursors to
CC       the large and small rRNAs (23S and 16S). Processes some mRNAs, and
CC       tRNAs when they are encoded in the rRNA operon. Processes pre-
CC       crRNA and tracrRNA of type II CRISPR loci if present in the
CC       organism. {ECO:0000256|HAMAP-Rule:MF_00104}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.;
CC         EC=3.1.26.3; Evidence={ECO:0000256|HAMAP-Rule:MF_00104,
CC         ECO:0000256|SAAS:SAAS01115986};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_00104, ECO:0000256|SAAS:SAAS00751453};
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00104,
CC       ECO:0000256|SAAS:SAAS00751513}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00104,
CC       ECO:0000256|SAAS:SAAS00751438}.
CC   -!- SIMILARITY: Belongs to the ribonuclease III family.
