OC Bacteria; Campylobacterota; Epsilonproteobacteria; Campylobacterales; OC Helicobacteraceae; Helicobacter. OX NCBI_TaxID=382638; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Sheeba; RX PubMed=16789826; DOI=10.1371/journal.pgen.0020120; RA Eppinger M., Baar C., Linz B., Raddatz G., Lanz C., Keller H., Morelli G., RA Gressmann H., Achtman M., Schuster S.C.; RT "Who ate whom? Adaptive Helicobacter genomic changes that accompanied a RT host jump from early humans to large felines."; RL PLoS Genet. 2:1097-1110(2006). 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}.
