Ribonuclease M5 (EC 3.1.26.8, RNase M5, 5S ribosomal maturation nuclease, 5S ribosomal RNA maturation endonuclease) is an enzyme.[1] This enzyme catalyses the following chemical reaction

Endonucleolytic cleavage of RNA, removing 21 and 42 nucleotides, respectively, from the 5'- and 3'-termini of a 5S-rRNA precursor

This enzyme converts the 5S-rRNA precursor from Bacillus subtilis into 5S-rRNA.
