OX NCBI_TaxID=430066; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=S19; RX PubMed=18478107; DOI=10.1371/journal.pone.0002193; RA Crasta O.R., Folkerts O., Fei Z., Mane S.P., Evans C., Martino-Catt S., RA Bricker B., Yu G., Du L., Sobral B.W.; RT "Genome sequence of Brucella abortus vaccine strain S19 compared to RT virulent strains yields candidate virulence genes."; RL PLoS ONE 3:E2193-E2193(2008). 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}.
