Transposable elements (TE), small mobile genetic elements unable to exist independently
of the host genome, were initially believed to be exclusively deleterious genomic parasites …

Small RNAs are ubiquitously present regulators in all kingdoms of life. Most bacterial and
archaeal small RNAs (sRNAs) act by antisense mechanisms on multiple target mRNAs …

Highlights•Hfq contacts RNA via proximal, distal, rim and C-terminal surfaces.•RNAs interact
with Hfq in multiple ways.•Mechanisms of Hfq-facilitated RNA pairing are being elucidated …

Most bacterial pathogens have the remarkable ability to flourish in the external environment
and in specialized host niches. This ability requires their metabolism, physiology, and …

Hfq is a ubiquitous, Sm‐like RNA binding protein found in most bacteria and some archaea.
Hfq binds small regulatory RNAs (sRNAs), facilitates base pairing between sRNAs and their …

During ribosomal and transfer RNA maturation, external transcribed spacer (ETS) and
internal transcribed spacer (ITS) sequences are excised and, as non-functional by-products …

Many bacteria use small RNA s (sRNA s) and the RNA chaperone Hfq to regulate mRNA
stability and translation. Hfq, a ring‐shaped homohexamer, has multiple faces that can bind …

There is an expanding list of examples by which one mRNA can posttranscriptionally
influence the expression of others. This can involve RNA sponges that sequester regulatory …

Research into post‐transcriptional control of mRNAs by small noncoding RNAs (sRNAs) in
the model bacteria Escherichia coli and Salmonella enterica has mainly focused on sRNAs …

Post-transcriptional regulation is a very important mechanism to control gene expression in
changing environments. In the past decade, a lot of interest has been directed toward the …
