OC Bacteria; Bacillota; Bacilli; Lactobacillales; Streptococcaceae; OC Streptococcus. OX NCBI_TaxID=561276; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=ATCC 700669 / Spain 23F-1; RX PubMed=19114491; DOI=10.1128/jb.01343-08; RA Croucher N.J., Walker D., Romero P., Lennard N., Paterson G.K., Bason N.C., RA Mitchell A.M., Quail M.A., Andrew P.W., Parkhill J., Bentley S.D., RA Mitchell T.J.; RT "Role of conjugative elements in the evolution of the multidrug-resistant RT pandemic clone Streptococcus pneumoniae Spain23F ST81."; RL J. Bacteriol. 191:1480-1489(2009). 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}.
