CC   -!- FUNCTION: Involved in mRNA degradation. Catalyzes the phosphorolysis of
CC       single-stranded polyribonucleotides processively in the 3'- to 5'-
CC       direction. Also involved, along with RNase II, in tRNA processing.
CC       RNases II and R contribute to rRNA degradation during starvation, while
CC       RNase R and PNPase are the major contributors to quality control of
CC       rRNA during steady state growth (PubMed:21135037). {ECO:0000255|HAMAP-

CC   -!- SUBUNIT: Component of the RNA degradosome, which is a multiprotein
CC       complex involved in RNA processing and mRNA degradation. Interacts with
CC       RNase E (rne). Homotrimer. The homotrimer forms a ring-like structure
CC       with a central channel, where RNA molecules can bind. RNA molecules
CC       bind between neighboring subunits. {ECO:0000255|HAMAP-Rule:MF_01595,

CC       ECO:0000269|PubMed:16079137}. Note=Has also been isolated in
CC       association with the inner membrane.
CC   -!- INDUCTION: Expression is negatively autoregulated at the translational
CC       level via an RNase III-dependent mechanism. Induced by cold shock (42
CC       to 15 degrees Celsius) (at protein level) (PubMed:8898389). At low
CC       temperature, the destabilizing effect of PNPase on its own mRNA is less
CC       efficient, leading to a decrease in repression and an increase in the
CC       expression level. {ECO:0000269|PubMed:11395447,
CC       ECO:0000269|PubMed:1628624, ECO:0000269|PubMed:8898389}.
CC   -!- DOMAIN: The S1 motif domain is important for trimerization and RNA-
CC       binding. {ECO:0000269|PubMed:18812438}.
CC   -!- SIMILARITY: Belongs to the polyribonucleotide nucleotidyltransferase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01595}.
