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 …

Despite the fact that much of the global microbial biosphere is believed to exist in high
pressure environments, the effects of hydrostatic pressure on microbial physiology remain …

The surge of antimicrobial resistance threatens efficacy of current antibiotics, particularly
against Pseudomonas aeruginosa, a highly resistant gram-negative pathogen. The …

Mutants in several genes have been obtained on the genetic background of virulent rough
(lacking O-polysaccharide) Brucella ovis PA. The target genes encode outer membrane …

Background Chloroplasts have evolved from a cyanobacterial endosymbiont and their
continuity has been maintained over time by chloroplast division, a process which is …

A superbly illustrated review presents the current molecular-level understanding of the key
structural complexes of the Gram-positive bacterium using Streptococcus pneumoniae as …

Vibrio cholerae is a natural inhabitant of aquatic environments and converts to a pathogen
upon infection by a filamentous phage, CTXΦ, that transmits the cholera toxin-encoding …

Because of ubiquity of thioesters, thioesterases play a critical role in metabolism, membrane
biosynthesis, signal transduction, and gene regulation. In many bacteria, YbgC is such an …

Highlights•HubP tethers chromosome origins and chemotactic signaling arrays to Vibrio
cholerae poles.•HubP and ParC ensure reliable inheritance of chemotactic signaling …

The clinical isolation rate of multidrug-resistant or pan-resistant Acinetobacter baumannii (A.
baumannii) is increasing, resulting that optional antibiotics are very limited in clinical …
