FUNCTION	Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
CATALYTIC ACTIVITY	Reaction=RNA(n+1) + phosphate = RNA(n) + a ribonucleoside 5'- diphosphate; Xref=Rhea:RHEA:22096, Rhea:RHEA-COMP:14527, Rhea:RHEA- COMP:17342, ChEBI:CHEBI:43474, ChEBI:CHEBI:57930, ChEBI:CHEBI:140395; EC=2.7.7.8;
COFACTOR	Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
case <OC:Gammaproteobacteria>
SUBUNIT	Component of the RNA degradosome, which is a multiprotein complex involved in RNA processing and mRNA degradation.
end case
SUBCELLULAR LOCATION	Cytoplasm.
SIMILARITY	Belongs to the polyribonucleotide nucleotidyltransferase family.
