OC Bacteria; Bacillota; Bacilli; Lactobacillales; Lactobacillaceae; OC Lactobacillus. OX NCBI_TaxID=257314; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=CNCM I-1225 / La1 / NCC 533; RX PubMed=14983040; DOI=10.1073/pnas.0307327101; RA Pridmore R.D., Berger B., Desiere F., Vilanova D., Barretto C., RA Pittet A.-C., Zwahlen M.-C., Rouvet M., Altermann E., Barrangou R., RA Mollet B., Mercenier A., Klaenhammer T., Arigoni F., Schell M.A.; RT "The genome sequence of the probiotic intestinal bacterium Lactobacillus RT johnsonii NCC 533."; RL Proc. Natl. Acad. Sci. U.S.A. 101:2512-2517(2004). 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}.
