ID RNPA_RICB8 Reviewed; 120 AA. AC A8GVL0; DT 15-JAN-2008, integrated into UniProtKB/Swiss-Prot. DT 13-NOV-2007, sequence version 1. DT 27-MAR-2024, entry version 78. 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=A1I_02565; OS Rickettsia bellii (strain OSU 85-389). OC Bacteria; Pseudomonadota; Alphaproteobacteria; Rickettsiales; OC Rickettsiaceae; Rickettsieae; Rickettsia; belli group. OX NCBI_TaxID=391896; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=OSU 85-389; RA Madan A., Lee H., Madan A., Yoon J.-G., Ryu G.-Y., Dasch G., Ereemeva M.; RT "Complete genome sequencing of Rickettsia bellii."; RL Submitted (SEP-2007) 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}.
