Molecular recognition of RhlB and RNase D in the Caulobacter crescentus RNA degradosome [PDF]

Nucleic Acids Research, 2014
The endoribonuclease RNase E is a key enzyme in RNA metabolism for many bacterial species. In Escherichia coli, RNase E contributes to the majority of RNA turnover and processing events, and the enzyme has been extensively characterized as the central component of the RNA degradosome assembly.

The DEAD-box RNA helicase CshA is required for fatty acid homeostasis in Staphylococcus aureus.

PLoS Genetics, 2020
Staphylococcus aureus is an opportunistic pathogen that can grow in a wide array of conditions: on abiotic surfaces, on the skin, in the nose, in planktonic or biofilm forms and can cause many type of infections. Consequently, S.

Polynucleotide phosphorylase has an impact on cell biology of Campylobacter jejuni [PDF]

, 2012
Polynucleotide phosphorylase (PNPase), encoded by the pnp gene, is known to degrade mRNA, mediating post-transcriptional regulation and may affect cellular functions. The role of PNPase is pleiotropic. As orthologs of the two major ribonucleases (RNase E

The contribution of mRNA targeting to spatial protein localization in bacteria

The FEBS Journal, Volume 291, Issue 21, Page 4639-4659, November 2024.
mRNA‐based targeting serves as a back‐up strategy for the canonical signal sequence‐based protein targeting in bacteria. While signal sequence‐based targeting depends on dedicated protein‐targeting factors, mRNAs encoding inner membrane proteins can bind directly to protein translocases.

Pseudomonas aeruginosa enolase influences bacterial tolerance to oxidative stresses and virulence

Frontiers in Microbiology, 2016
Pseudomonas aeruginosa is a Gram negative opportunistic pathogenic bacterium, which causes acute and chronic infections. Upon entering host, bacteria alter global gene expression to adapt to host environment and avoid clearance by host.

The Conserved Dcw Gene Cluster of R. sphaeroides Is Preceded by an Uncommonly Extended 5’ Leader Featuring the sRNA UpsM [PDF]

, 2016
Cell division and cell wall synthesis mechanisms are similarly conserved among bacteria. Consequently some bacterial species have comparable sets of genes organized in the dcw (division and cell wall) gene cluster.

Recognition of the 70S ribosome and polysome by the RNA degradosome in Escherichia coli [PDF]

Nucleic Acids Research, 2012
The RNA degradosome is a multi-enzyme assembly that contributes to key processes of RNA metabolism, and it engages numerous partners in serving its varied functional roles. Small domains within the assembly recognize collectively a diverse range of macromolecules, including the core protein components, the cytoplasmic lipid membrane, mRNAs, non-coding ...

Escherichia coli strains with precise domain deletions in the ribonuclease RNase E can achieve greatly enhanced levels of membrane protein production

Protein Science, Volume 33, Issue 2, February 2024.
Abstract Escherichia coli is one of the most widely utilized hosts for production of recombinant membrane proteins (MPs). Bacterial MP production, however, is usually accompanied by severe toxicity and low‐level volumetric accumulation. In previous work, we had discovered that co‐expression of RraA, an inhibitor of the RNA‐degrading activity of RNase E,
