CC   -!- FUNCTION: Digests double-stranded RNA. Involved in the processing of
CC       primary rRNA transcript to yield the immediate precursors to the large
CC       and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when
CC       they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA
CC       of type II CRISPR loci if present in the organism. {ECO:0000255|HAMAP-
CC       Rule:MF_00104}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.; EC=3.1.26.3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00104};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00104};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00104}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00104}.
CC   -!- SIMILARITY: Belongs to the ribonuclease III family. {ECO:0000255|HAMAP-
CC       Rule:MF_00104}.
