Post-transcriptional addition of poly (A) tails to the 3′ end of RNA is one of the fundamental
events controlling the functionality and fate of RNA in all kingdoms of life. Although an …

Polyadenylation is a posttranscriptional modification present throughout all the kingdoms of
life with important roles in regulation of RNA stability, translation, and quality control …

Polyadenylation is a postranscriptional modification of RNA found in all cells and in
organelles. In bacteria, a small fraction of RNA harbors oligo (A) tails which are mostly …

Although the first poly (A) polymerase (PAP) was discovered in Escherichia coli in 1962, the
study of polyadenylation in bacteria was largely ignored for the next 30 years. However, with …

In bacteria, most mRNAs and certain regulatory RNAs are rapidly turned over, whereas
mature tRNA and ribosomal RNA are highly stable. The selective susceptibility of unstable …

Polyadenylation is thought to be involved in the degradation and quality control of bacterial
RNAs but relatively few examples have been investigated. We used a combination of 5΄ …

The posttranscriptional addition of poly (A) extensions to RNA is a phenomenon common to
almost all organisms. In eukaryotes, a stable poly (A) tail is added to the 3′‐end of most …

Polyadenylation at the 3′ terminus has long been considered a specific feature of mRNA
and a few other unstable RNA species. Here we show that stable RNAs in Escherichia coli …

The 3′-ends of both prokaryotic and eukaryotic mRNA are polyadenylated, but the poly (A)
tracts of prokaryotic mRNA are generally shorter, ranging from 15 to 60 adenylate residues …

Poly (A) tails in Escherichia coli are hypothesized to provide unstructured single‐stranded
substrates that facilitate the degradation of mRNAs by ribonucleases. Here, we have …
