RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA].
RA Nijsse Bart;
RL Submitted (MAR-2015) to the EMBL/GenBank/DDBJ databases.
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:0000256|HAMAP-Rule:MF_01468}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-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}.
