OC Bacteria; Bacillota; Bacilli; Lactobacillales; Lactobacillaceae; OC Lactobacillus. OX NCBI_TaxID=405566; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=DPC 4571; RX PubMed=17993529; DOI=10.1128/jb.01295-07; RA Callanan M., Kaleta P., O'Callaghan J., O'Sullivan O., Jordan K., RA McAuliffe O., Sangrador-Vegas A., Slattery L., Fitzgerald G.F., RA Beresford T., Ross R.P.; RT "Genome sequence of Lactobacillus helveticus: an organism distinguished by RT selective gene loss and IS element expansion."; RL J. Bacteriol. 190:727-735(2008). 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}.
