CC   -!- FUNCTION: Involved in mRNA degradation. Catalyzes the phosphorolysis of
CC       single-stranded polyribonucleotides processively in the 3'- to 5'-
CC       direction. {ECO:0000255|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       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|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:0000255|HAMAP-Rule:MF_01595}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01595}.
CC   -!- SIMILARITY: Belongs to the polyribonucleotide nucleotidyltransferase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01595}.
