CC   -!- FUNCTION: Phosphorolytic 3'-5' exoribonuclease that plays an
CC       important role in tRNA 3'-end maturation. Removes nucleotide
CC       residues following the 3'-CCA terminus of tRNAs; can also add
CC       nucleotides to the ends of RNA molecules by using nucleoside
CC       diphosphates as substrates, but this may not be physiologically
CC       important. Probably plays a role in initiation of 16S rRNA
CC       degradation (leading to ribosome degradation) during starvation.
CC       {ECO:0000255|HAMAP-Rule:MF_00564}.
CC   -!- CATALYTIC ACTIVITY: tRNA(n+1) + phosphate = tRNA(n) + a nucleoside
CC       diphosphate. {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}.
