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 …

Bacteria survive in highly dynamic and complex environments due, in part, to the presence
of systems that allow the rapid control of gene expression in the presence of changing …

The OprF porin is the major outer membrane protein of Pseudomonas aeruginosa. OprF is
involved in several crucial functions, including cell structure, outer membrane permeability …

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 …

SigX is one of the 19 extracytoplasmic function sigma factors that have been predicted in the
human opportunistic pathogen Pseudomonas aeruginosa genome. SigX is involved in the …

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 …
