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}.
