Regulation of the Salmonella typhimurium flavohemoglobin gene. A new pathway for bacterial gene expression in response to nitric oxide.

Journal of Biological Chemistry, 1998
Flavohemoglobins, a family of two-domain proteins with homology to vertebrate hemoglobins, are found in a variety of prokaryotic and eukaryotic microorganisms. Recent studies suggest a role for these proteins in nitrogen oxide metabolism.

Pseudomonas aeruginosa Polynucleotide Phosphorylase Contributes to Ciprofloxacin Resistance by Regulating PrtR

Frontiers in Microbiology, 2019
Pseudomonas aeruginosa is an opportunistic bacterial pathogen that causes various acute and chronic infections. It is intrinsically resistant to a variety of antibiotics. However, production of pyocins during SOS response sensitizes P.

RpoN2- and FliA-regulated fliTX is indispensible for flagellar motility and virulence in Xanthomonas oryzae pv. oryzae

BMC Microbiology, 2017
Background Bacterial blight of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most important crop diseases in the world. More insights into the mechanistic regulation of bacterial pathogenesis will help us identify novel molecular ...

Regulation of virulence gene expression

Virulence, 2014
The bacterial pathogen that finds itself, either by accident or design, within the human or animal host, senses and adapts to the prevailing conditions by modulating its gene expression on a global scale.

Regulation of bacterial gene expression by the NTP substrates of transcription initiation [PDF]

Molecular Microbiology, 2008
SummaryMany mechanisms of gene regulation in bacteria do not employ repressor or activator proteins. One class of these mechanisms includes those in which the key regulatory element is the control of transcription initiation by the availability of NTP substrates.

Effects of Population Dynamics on Establishment of a Restriction-Modification System in a Bacterial Host

Molecules, 2019
In vivo dynamics of protein levels in bacterial cells depend on both intracellular regulation and relevant population dynamics. Such population dynamics effects, e.g., interplay between cell and plasmid division rates, are, however, often neglected in ...

MTS1338, A Small Mycobacterium tuberculosis RNA, Regulates Transcriptional Shifts Consistent With Bacterial Adaptation for Entering Into Dormancy and Survival Within Host Macrophages

Frontiers in Cellular and Infection Microbiology, 2019
Small non-coding RNAs play a significant role in bacterial adaptation to changing environmental conditions. We investigated the dynamics of expression of MTS1338, a small non-coding RNA of Mycobacterium tuberculosis, in the mouse model in vivo ...

Novel algorithms reveal streptococcal transcriptomes and clues about undefined genes.

PLoS Computational Biology, 2007
Bacteria-host interactions are dynamic processes, and understanding transcriptional responses that directly or indirectly regulate the expression of genes involved in initial infection stages would illuminate the molecular events that result in host ...

Comparative transcriptome and phenotype analysis revealed the role and mechanism of ompR in the virulence of fish pathogenic Aeromonas hydrophila

MicrobiologyOpen, 2020
Aeromonas hydrophila B11 strain was isolated from diseased Anguilla japonica, which had caused severe gill ulcers in farmed eel, causing huge economic losses. EnvZ‐OmpR is a model two‐component system in the bacteria and is widely used in the research of
