OX NCBI_TaxID=272947; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Madrid E; RX PubMed=9823893; DOI=10.1038/24094; RA Andersson S.G.E., Zomorodipour A., Andersson J.O., Sicheritz-Ponten T., RA Alsmark U.C.M., Podowski R.M., Naeslund A.K., Eriksson A.-S., Winkler H.H., RA Kurland C.G.; RT "The genome sequence of Rickettsia prowazekii and the origin of RT mitochondria."; RL Nature 396:133-140(1998). 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}.
