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}.
