RNA degradation in Escherichia coli regulated by 3' adenylation and 5' phosphorylation.

Nature - 9 Mar 1995

Xu F, Cohen S N

Abstract excerpt

Although polyadenylation has commonly been regarded as a special feature of eukaryotic messenger RNA, there are many reports of polyA tails on bacterial RNA (for example, refs 3-8). In Escherichia coli, adenylation mediated by the pcnB gene greatly accelerates decay of RNA I, an antisense repressor of replication of ColE1 type plasmids that resembles highly structured transfer RNA but shows the rapid turnover...
