CC   -!- FUNCTION: Phosphorolytic 3'-5' exoribonuclease that plays an important
CC       role in tRNA 3'-end maturation. Removes nucleotide residues following
CC       the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of
CC       RNA molecules by using nucleoside diphosphates as substrates, but this
CC       may not be physiologically important. Probably plays a role in
CC       initiation of 16S rRNA degradation (leading to ribosome degradation)
CC       during starvation. {ECO:0000255|HAMAP-Rule:MF_00564}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=phosphate + tRNA(n+1) = a ribonucleoside 5'-diphosphate +
CC         tRNA(n); Xref=Rhea:RHEA:10628, Rhea:RHEA-COMP:17343, Rhea:RHEA-
CC         COMP:17344, ChEBI:CHEBI:43474, ChEBI:CHEBI:57930, ChEBI:CHEBI:173114;
CC         EC=2.7.7.56; Evidence={ECO:0000255|HAMAP-Rule:MF_00564};
CC   -!- SUBUNIT: Homohexameric ring arranged as a trimer of dimers.
CC       {ECO:0000255|HAMAP-Rule:MF_00564}.
CC   -!- SIMILARITY: Belongs to the RNase PH family. {ECO:0000255|HAMAP-
CC       Rule:MF_00564}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAT83406.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
