Pyoverdine siderophores: from biogenesis to biosignificance.
Pyoverdines are a group of structurally related siderophores produced by fluorescent Pseudomonas species and the extremely high sequence diversity of genes involved in pyoverdine synthesis and uptake indicate that py overdine production is subject to high evolutionary pressure. Expand
Iron transport and regulation, cell signalling and genomics: lessons from Escherichia coli and Pseudomonas
Recent advances in understanding of PvdS and FecI, a distinct subfamily of ECF sigma factors involved in iron acquisition and hence named the iron‐starvation sigmas, are reviewed. Expand
Acinetobacter baumannii: evolution of a global pathogen.
The recent expansion of A. baumannii sequenced genomes has permitted the development of large-array phylogenomic and phenotypic analyses, which can offer valuable insights into the evolution and adaptation of the human pathogen. Expand
The response to stationary‐phase stress conditions in Escherichia coli : role and regulation of the glutamic acid decarboxylase system
In vivo evidence is provided that gadC is co‐transcribed with gadB and that the functional glutamic acid‐dependent system requires the activities of both GadA/B and GadC, and that expression of gad genes is positively regulated by acidic shock, salt stress and stationary growth phase. Expand
Palmitoylation-dependent estrogen receptor alpha membrane localization: regulation by 17beta-estradiol.
The physiological role of ERalpha palmitoylation in the receptor localization to the cell membrane and in the regulation of the E2-induced cell proliferation are found. Expand
Whole-Genome Pyrosequencing of an Epidemic Multidrug-Resistant Acinetobacter baumannii Strain Belonging to the European Clone II Group
The whole-genome sequence of an epidemic, multidrug-resistant Acinetobacter baumannii strain (strain ACICU) belonging to the European clone II group and carrying the plasmid-mediated blaOXA-58 carbapenem resistance gene was determined, providing novel insight into the genetic basis of A. baumANNii resistance.

Burkholderia cepacia complex species: health hazards and biotechnological potential.
The Burkholderia cepacia complex is a group of nine closely related bacterial species that have useful properties in the natural environment as plant pest antagonists, plant growth promoters andExpand
Functional characterization and regulation of gadX, a gene encoding an AraC/XylS-like transcriptional activator of the Escherichia coli glutamic acid decarboxylase system.
It is demonstrated that transcription of both gadA and gadBC is positively controlled by gadX, a gene downstream of gadA, encoding a transcriptional regulator belonging to the AraC/XylS family. Expand
Deciphering the Multifactorial Nature of Acinetobacter baumannii Pathogenicity
Evidence of the multifactorial nature of A. baumannii virulence is provided, as several virulence factors, including exoproducts with hemolytic, phospholipase, protease and iron-chelating activities, as well as a number of multi-ifactorial phenotypes, such as biofilm formation, surface motility and stress resistance, which were differentially expressed and could play a role in A. Baumanni pathogenicity. Expand
Structural genes for salicylate biosynthesis from chorismate in Pseudomonas aeruginosa
Results are consistent with a pathway leading from chorismate to isochorismating and then to salicylate plus pyruvate, catalyzed consecutively by the iron-repressible PchA and PchB proteins in P. aeruginosa. Expand
