CC -!- FUNCTION: Zinc phosphodiesterase, which displays some tRNA 3'-
CC processing endonuclease activity. Probably involved in tRNA maturation,
CC by removing a 3'-trailer from precursor tRNA. {ECO:0000255|HAMAP-
CC Rule:MF_01818}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage of RNA, removing extra 3' nucleotides
CC from tRNA precursor, generating 3' termini of tRNAs. A 3'-hydroxy
CC group is left at the tRNA terminus and a 5'-phosphoryl group is left
CC at the trailer molecule.; EC=3.1.26.11; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01818};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01818};
CC Note=Binds 2 Zn(2+) ions. {ECO:0000255|HAMAP-Rule:MF_01818};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01818}.
CC -!- SIMILARITY: Belongs to the RNase Z family. {ECO:0000255|HAMAP-
CC Rule:MF_01818}.
