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}.
