Photorhabdus lux-operon heat shock-like regulation

Heliyon, 2023
For decades, transcription of Photorhabdus luminescens lux-operon was considered being constitutive. Therefore, this lux-operon has been used for measurements in non-specific bacterial luminescent biosensors.

Network Topology as a Driver of Bistability in the lac Operon

, 2008
The lac operon in Escherichia coli has been studied extensively and is one of the earliest gene systems found to undergo both positive and negative control. The lac operon is known to exhibit bistability, in the sense that the operon is either induced or

An NMR Study on the clpC Operon Binding Region of Transcription Factor CtsR from Bacillus subtilis

Chinese Journal of Magnetic Resonance, 2021
When Gram-positive bacterium Bacillus subtilis responds to heat-shock, protein arginine kinase McsB phosphorylates Arg62 (R) in the clpC operon binding region of transcription factor CtsR, leading to dissociation of CtsR and clpC operon and initiation of

Sequence Variability of P2-Like Prophage Genomes Carrying the Cytolethal Distending Toxin V Operon in Escherichia coli O157 [PDF]

, 2013
Cytolethal distending toxins (CDT) are potent cytotoxins of several Gram-negative pathogenic bacteria, including Escherichia coli, in which five types (CDT-I to CDT-V) have been identified so far.

Probable Role of Type IV Pili of Aeromonas hydrophila in Human Pathogenicity

Pathogens
Background: Aeromonas hydrophila is a widely recognized broad-spectrum pathogen that primarily targets the gastrointestinal tract. Type IV pili (T4P) are proteinaceous nano-machines located on the bacterial cell surface, playing a crucial role in host ...
