Compensatory evolution of chromosomes and plasmids counteracts the plasmid fitness cost
Ecology and Evolution, Volume 14, Issue 8, August 2024.In this review, we provide a comprehensive overview of the currently reported mechanisms underlying compensatory evolution on chromosomes and plasmids, elucidate key targets regulating plasmid fitness cost, and discuss future challenges in this field.

Interconnection of post-transcriptional regulation: The RNA-binding protein Hfq is a novel target of the Lon protease in Pseudomonas aeruginosa [PDF]
, 2015 Besides being a major opportunistic human pathogen, Pseudomonas aeruginosa can be found in a wide range of environments. This versatility is linked to complex regulation, which is achieved through the action of transcriptional regulators, and post ...

Identification of protein-protein and ribonucleoprotein complexes containing Hfq [PDF]
Scientific Reports, 2019 AbstractHfq is a RNA-binding protein that plays a pivotal role in the control of gene expression in bacteria by stabilizing sRNAs and facilitating their pairing with multiple target mRNAs. It has already been shown that Hfq, directly or indirectly, interacts with many proteins: RNase E, Rho, poly(A)polymerase, RNA polymerase… In order to detect more ...

Distinctive Regulation of Carbapenem Susceptibility in Pseudomonas aeruginosa by Hfq
Frontiers in Microbiology, 2020 Carbapenems are often the antibiotics of choice to combat life threatening infections caused by the opportunistic human pathogen Pseudomonas aeruginosa. The outer membrane porins OprD and OpdP serve as entry ports for carbapenems.

The orthosymplectic superalgebra in harmonic analysis [PDF]
, 2012 We introduce the orthosymplectic superalgebra osp(m|2n) as the algebra of Killing vector fields on Riemannian superspace R^{m|2n} which stabilize the origin. The Laplace operator and norm squared on R^{m|2n}, which generate sl(2), are orthosymplectically

Nuclear spin squeezing via electric quadrupole interaction [PDF]
, 2016 Control over nuclear spin fluctuations is essential for processes that rely on preserving the quantum state of an embedded system. For this purpose, squeezing is a viable alternative, so far that has not been properly exploited for the nuclear spins.

Molecular Microbiology, Volume 122, Issue 1, Page 11-28, July 2024.The E. coli rpoN operon encodes important regulatory proteins including sigma 54 and components of the nitrogen‐related PTS. Here we show that additional upstream and internally located promoters contribute to its transcription in response to distinct envelope stress conditions and carbon source quality. RNase E cleaves transcripts extensively upstream

mSystems, 2019 Bacterial small noncoding RNAs (sRNAs) play posttranscriptional regulatory roles in cellular responses to changing environmental cues and in adaptation to harsh conditions. Generally, the RNA-binding protein Hfq helps sRNAs associate with target mRNAs to
