CC   -!- FUNCTION: Involved in correct processing of both the 5' and 3' ends of
CC       23S rRNA precursor. Processes 30S rRNA precursor transcript even in
CC       absence of ribonuclease 3 (Rnc); Rnc processes 30S rRNA into smaller
CC       rRNA precursors. {ECO:0000255|HAMAP-Rule:MF_01468}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01468};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01468}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01468}.
CC   -!- SIMILARITY: Belongs to the MrnC RNase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01468}.
