ID RNPA_THEAQ Reviewed; 162 AA. AC Q7X5L4; DT 29-MAR-2004, integrated into UniProtKB/Swiss-Prot. DT 01-OCT-2003, sequence version 1. DT 08-NOV-2023, entry version 68. 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}; OS Thermus aquaticus. OC Bacteria; Deinococcota; Deinococci; Thermales; Thermaceae; Thermus. OX NCBI_TaxID=271; RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC DNA]. RC STRAIN=EP 00276; RX PubMed=12719542; DOI=10.1073/pnas.0931462100; RA Feltens R., Gossringer M., Willkomm D.K., Urlaub H., Hartmann R.K.; RT "An unusual mechanism of bacterial gene expression revealed for the RNase P RT protein of Thermus strains."; RL Proc. Natl. Acad. Sci. U.S.A. 100:5724-5729(2003). 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 -!- MISCELLANEOUS: The open reading frame (ORF) for this protein entirely CC encompasses the ORF for the 50S ribosomal protein L34 (rpmH). The two CC start codons are separated by four nucleotides. CC -!- SIMILARITY: Belongs to the RnpA family. {ECO:0000255|HAMAP- CC Rule:MF_00227}.
