CC   -!- FUNCTION: RNA-free RNase P that catalyzes the removal of the 5'-leader
CC       sequence from pre-tRNA to produce the mature 5'-terminus.
CC       {ECO:0000255|HAMAP-Rule:MF_01078}.
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_01078};
CC   -!- SIMILARITY: Belongs to the HARP family. {ECO:0000255|HAMAP-
CC       Rule:MF_01078}.
