Gene name Name=mrnC;

Comments [?]

FUNCTIONInvolved in correct processing of both the 5' and 3' ends of 23S rRNA precursor. Processes 30S rRNA precursor transcript even in absence of ribonuclease 3 (Rnc); Rnc processes 30S rRNA into smaller rRNA precursors.
COFACTOR Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
SIMILARITYBelongs to the MrnC RNase family.
