The Gram-negative envelope is a complex structure that consists of the inner membrane, the
periplasm, peptidoglycan and the outer membrane, and protects the bacterial cell from the …

Bacterial biofilms can cause medical problems and issues in technical systems. While a
large body of knowledge exists on the phenotypes of planktonic and of sessile cells in …

Conditions that impair protein folding in the Gram‐negative bacterial envelope cause stress.
The destabilizing effects of stress in this compartment are recognized and countered by a …

The formation of biofilm results in a major lifestyle switch that is thought to affect the
expression of multiple genes and operons. We used DNA arrays to study the global effect of …

ABSTRACT A novel plasmid-mediated quinolone resistance gene, qnrB, has been
discovered in a plasmid encoding the CTX-M-15 β-lactamase from a Klebsiella pneumoniae …

The phage‐shock‐protein (Psp) system responds to extracytoplasmic stress that may reduce
the energy status of the cell. It is conserved in many different bacteria and has been linked to …

The bacterial phage shock protein (Psp) response functions to help cells manage the
impacts of agents impairing cell membrane function. The system has relevance to …

SUMMARY ς54 has several features that distinguish it from other sigma factors in
Escherichia coli: it is not homologous to other ς subunits, ς54-dependent expression …

The bacterial cell envelope is a protective barrier at the frontline of bacterial interaction with
the environment, and its integrity is regulated by various stress response systems. The Rcs …

The phage‐shock‐protein (psp) operon helps to ensure survival of Escherichia coli in late
stationary phase at alkaline pH, and protects the cell against dissipation of its proton‐motive …
