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}.
