RL Submitted (JUL-2018) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Involved in mRNA degradation. Catalyzes the phosphorolysis of
CC single-stranded polyribonucleotides processively in the 3'- to 5'-
CC direction. {ECO:0000256|HAMAP-Rule:MF_01595}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=phosphate + RNA(n+1) = a ribonucleoside 5'-diphosphate +
CC RNA(n); Xref=Rhea:RHEA:22096, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC COMP:17342, ChEBI:CHEBI:43474, ChEBI:CHEBI:57930, ChEBI:CHEBI:140395;
CC EC=2.7.7.8; Evidence={ECO:0000256|HAMAP-Rule:MF_01595};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01595};
CC -!- SUBUNIT: Component of the RNA degradosome, which is a multiprotein
CC complex involved in RNA processing and mRNA degradation.
CC {ECO:0000256|HAMAP-Rule:MF_01595}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01595}.
CC -!- SIMILARITY: Belongs to the polyribonucleotide nucleotidyltransferase
CC family. {ECO:0000256|ARBA:ARBA00007404, ECO:0000256|HAMAP-
CC Rule:MF_01595}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
