OC Bacteria; Bacillota; Bacilli; Lactobacillales; Streptococcaceae; OC Streptococcus. OX NCBI_TaxID=193567; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=SSI-1; RX PubMed=12799345; DOI=10.1101/gr.1096703; RA Nakagawa I., Kurokawa K., Yamashita A., Nakata M., Tomiyasu Y., RA Okahashi N., Kawabata S., Yamazaki K., Shiba T., Yasunaga T., Hayashi H., RA Hattori M., Hamada S.; RT "Genome sequence of an M3 strain of Streptococcus pyogenes reveals a large- RT scale genomic rearrangement in invasive strains and new insights into phage RT evolution."; RL Genome Res. 13:1042-1055(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 -!- SIMILARITY: Belongs to the RnpA family. {ECO:0000255|HAMAP- CC Rule:MF_00227}.
