Bacteria often encounter temperature fluctuations in their natural habitats and must adapt to
survive. The molecular response of bacteria to sudden temperature upshift or downshift is …

The continuous degradation and synthesis of prokaryotic mRNAs not only give rise to the
metabolic changes that are required as cells grow and divide but also rapid adaptation to …

Temperature influences the structural and functional properties of cellular components,
necessitating stress responses to restore homeostasis following temperature shift. Whereas …

The RNA degradosome of Escherichia coli is a multiprotein complex involved in the
degradation of mRNA. The principal components are RNase E, PNPase, RhlB, and enolase …

Degradation of RNA plays a central role in RNA metabolism. In recent years, our knowledge
of the mechanisms of RNA degradation has increased considerably with discovery of the …

Survival of bacteria at low temperatures provokes scientific interest because of several
reasons. Investigations in this area promise insight into one of the mysteries of life science …

The instability of messenger RNA is fundamental to the control of gene expression. In
bacteria, mRNA degradation generally follows an “all-or-none” pattern. This implies that if …

In most organisms, dedicated multiprotein complexes, called exosome or RNA
degradosome, carry out RNA degradation and processing. In addition to varying …

RNA helicases function as molecular motors that rearrange RNA secondary structure,
potentially performing roles in any cellular process involving RNA metabolism. Although …

Instability is a fundamental property of mRNA that is necessary for the regulation of gene
expression. In E. coli, the turnover of mRNA involves multiple, redundant pathways involving …
