CC -!- FUNCTION: Required for correct processing of both the 5' and 3' ends of
CC 5S rRNA precursor. Cleaves both sides of a double-stranded region
CC yielding mature 5S rRNA in one step. Releases 5'-phosphoryl and 3'-
CC hydroxy termini. {ECO:0000255|HAMAP-Rule:MF_01469,
CC ECO:0000269|PubMed:402365, ECO:0000269|PubMed:4215038}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage of RNA, removing 21 and 42
CC nucleotides, respectively, from the 5'- and 3'-termini of a 5S-rRNA
CC precursor.; EC=3.1.26.8; Evidence={ECO:0000255|HAMAP-Rule:MF_01469};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000269|PubMed:402365};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000269|PubMed:402365};
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000269|PubMed:402365};
CC Note=Divalent metal cations; Mg(2+) > Mn(2+) > Ca(2+).
CC {ECO:0000269|PubMed:402365};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 7-8.5 at 37 degrees Celsius.
CC {ECO:0000269|PubMed:402365};
CC -!- SUBUNIT: Requires ribosomal protein L18 (rplR) for catalysis; it can be
CC replaced by 30% dimethylsulfoxide suggesting L18 functions as an rRNA
CC folding chaperone. {ECO:0000269|PubMed:402365}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01469,
CC ECO:0000269|PubMed:11233981, ECO:0000269|PubMed:402365}.
CC Note=Associated with 70S ribosomes.
CC -!- DISRUPTION PHENOTYPE: Not essential. Accumulation of precursor forms of
CC 5S rRNA in total, ribosomes and polysome RNA preparations; smaller
CC forms (126 and 135 nucleotides) are predominantly found in ribosomes
CC and polysomes. Each of the 10 rrn operons gives rise to a different 5S
CC rRNA precursor due to differences in their 3' ends.
CC {ECO:0000269|PubMed:11233981, ECO:0000269|PubMed:16077031}.
CC -!- SIMILARITY: Belongs to the ribonuclease M5 family. {ECO:0000255|HAMAP-
CC Rule:MF_01469}.
