RC STRAIN=Okra / Type B1; RX PubMed=18060065; DOI=10.1371/journal.pone.0001271; RA Smith T.J., Hill K.K., Foley B.T., Detter J.C., Munk A.C., Bruce D.C., RA Doggett N.A., Smith L.A., Marks J.D., Xie G., Brettin T.S.; RT "Analysis of the neurotoxin complex genes in Clostridium botulinum A1-A4 RT and B1 strains: BoNT/A3, /Ba4 and /B1 clusters are located within RT plasmids."; RL PLoS ONE 2:E1271-E1271(2007). CC -!- FUNCTION: RNaseP catalyzes the removal of the 5'-leader sequence from CC pre-tRNA to produce the mature 5'-terminus. It can also cleave other CC RNA substrates such as 4.5S RNA. The protein component plays an CC auxiliary but essential role in vivo by binding to the 5'-leader CC sequence and broadening the substrate specificity of the ribozyme. CC {ECO:0000255|HAMAP-Rule:MF_00227}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Endonucleolytic cleavage of RNA, removing 5'-extranucleotides CC from tRNA precursor.; EC=3.1.26.5; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00227}; CC -!- SUBUNIT: Consists of a catalytic RNA component (M1 or rnpB) and a CC protein subunit. {ECO:0000255|HAMAP-Rule:MF_00227}. CC -!- SIMILARITY: Belongs to the RnpA family. {ECO:0000255|HAMAP- CC Rule:MF_00227}.
