ID RNPA_HELPS Reviewed; 161 AA. AC B2UVJ3; DT 24-MAR-2009, integrated into UniProtKB/Swiss-Prot. DT 01-JUL-2008, sequence version 1. DT 27-MAR-2024, entry version 75. DE RecName: Full=Ribonuclease P protein component {ECO:0000255|HAMAP-Rule:MF_00227}; DE Short=RNase P protein {ECO:0000255|HAMAP-Rule:MF_00227}; DE Short=RNaseP protein {ECO:0000255|HAMAP-Rule:MF_00227}; DE EC=3.1.26.5 {ECO:0000255|HAMAP-Rule:MF_00227}; DE AltName: Full=Protein C5 {ECO:0000255|HAMAP-Rule:MF_00227}; GN Name=rnpA {ECO:0000255|HAMAP-Rule:MF_00227}; GN OrderedLocusNames=HPSH_07410; OS Helicobacter pylori (strain Shi470). OC Bacteria; Campylobacterota; Epsilonproteobacteria; Campylobacterales; OC Helicobacteraceae; Helicobacter. OX NCBI_TaxID=512562; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Shi470; RA Kersulyte D., Kalia A., Gilman R.H., Berg D.E.; RT "Genome sequence of Helicobacter pylori from the remote Amazon: traces of RT Asian ancestry of the first Americans."; RL Submitted (MAY-2008) to the EMBL/GenBank/DDBJ databases. 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}.
