Pseudomonas putida is a fast-growing bacterium found mostly in temperate soil and water
habitats. The metabolic versatility of P. putida makes this organism attractive for …

Pseudomonas aeruginosa can develop resistance to polymyxin as a consequence of
mutations in the PhoPQ regulatory system, mediated by covalent lipid A modification …

Transcriptional responses of microorganisms to environmental perturbations are broad and
complex, and often involve regulatory cascades in which an interplay of regulatory factors …

Chromosomal toxin-antitoxin (TA) systems are widespread among free-living bacteria and
are supposedly involved in stress tolerance. Here, we report the first TA system identified in …

Abstract Background The ColRS two-component system has been shown to contribute to the
membrane functionality and stress tolerance of Pseudomonas putida as well as to the …

ABSTRACT TonB-ExbB-ExbD-like energy transduction systems are widespread among
Gram-negative bacteria. While most species have only one copy of tonB-e xbBD genes, the …

Background We have recently found that Pseudomonas putida deficient in ColRS two-
component system is sensitive to phenol and displays a serious defect on solid glucose …

Zinc is an important micronutrient for bacteria, but its excess is toxic. Recently, the ColRS
two-component system was shown to detect and respond to zinc excess and to contribute to …

Life is full of stress. This is true for us, but even more so for unicellular organisms like
bacteria. Bacteria inhabit a wide variety of different environments and often encounter very …

Background Conserved two-component system ColRS of Pseudomonas genus has been
implicated in several unrelated phenotypes. For instance, deficiency of P. putida ColRS …
