Comments [?]

Function Involved 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 Mg(2+)
Subunit Homodimer.
Subcellular location Cytoplasm.
Similarity Belongs to the MrnC RNase family.
