CC   -!- FUNCTION: Involved in correct processing of both the 5' and 3'
CC       ends of 23S rRNA precursor. Processes 30S rRNA precursor
CC       transcript even in absence of ribonuclease 3 (Rnc); Rnc processes
CC       30S rRNA into smaller rRNA precursors. {ECO:0000256|HAMAP-
CC       Rule:MF_01468}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01468};
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01468}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01468}.
CC   -!- SIMILARITY: Belongs to the MrnC RNase family. {ECO:0000256|HAMAP-
CC       Rule:MF_01468}.
CC   -!- CAUTION: The sequence shown here is derived from an
CC       EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is
CC       preliminary data. {ECO:0000313|EMBL:EAQ69061.1}.
