ID RNPA_LEGPC Reviewed; 114 AA. AC A5IIK5; DT 15-JAN-2008, integrated into UniProtKB/Swiss-Prot. DT 26-JUN-2007, sequence version 1. DT 28-JAN-2026, entry version 83. 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=LPC_3319; OS Legionella pneumophila (strain Corby). OC Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; OC Legionellales; Legionellaceae; Legionella. OX NCBI_TaxID=400673; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Corby; RA Gloeckner G., Albert-Weissenberger C., Weinmann E., Jacobi S., Schunder E., RA Steinert M., Buchrieser C., Hacker J., Heuner K.; RT "Identification and characterization of a new conjugation/ type IVA RT secretion system (trb/tra) of L. pneumophila Corby localized on a mobile RT genomic island."; RL Submitted (NOV-2006) 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}.
