5S rRNA precursor + H2O the enzyme cleaves twice in double-helical region of a 179-nucleotide precursor of 5S rRNA to yield mature 5S rRNA of 116 nucleotides plus fragments of 21 and 42 nucleotides. The conformation, not sequence, is the important feature in the locale of the cleaved bonds Bacillus subtilis mature 5S rRNA + oligonucleotides

5S rRNA precursor + H2O the 5'-precursor-specific segment contains one or more components recognized by RNase M5 during its interaction with the p5A substrate Bacillus subtilis mature 5S rRNA + oligonucleotides

?
additional information the artificial substrate lacking the 5'-terminal precursor segment is cleaved very much more slowly than that lacking 3' segment Bacillus subtilis ?
