EC 3.1.26.8

Accepted name: ribonuclease M5

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

Other name(s): RNase M5; 5S ribosomal maturation nuclease; 5S ribosomal RNA maturation endonuclease

Comments: Converts the 5S-rRNA precursor from Bacillus subtilis into 5S-rRNA, with 5'-phosphate and 3'-hydroxy groups.
