The Fluidity of the Bacterial Outer Membrane Is Species Specific
BioEssays, 2020 AbstractThe outer membrane (OM) is an essential barrier that guards Gram‐negative bacteria from diverse environmental insults. Besides functioning as a chemical gatekeeper, the OM also contributes towards the strength and stiffness of cells and allows them to sustain mechanical stress. Largely influenced by studies of Escherichia coli, the OM is viewed

Outer membrane permeabilization is an essential step in the killing of gram-negative bacteria by the lectin RegIIIβ. [PDF]
PLoS ONE, 2013 The C-type lectin RegIIIβ can kill certain Gram-positive and Gram-negative bacteria. The susceptibility of S. Typhimurium depends on the bacterial growth phase, i.e., bacteria from the logarithmic growth phase do bind RegIIIβ and are subsequently killed.

The bacterial outer membrane is an evolving antibiotic barrier [PDF]
Proceedings of the National Academy of Sciences, 2018 The outer membrane (OM) of the diderm “gram-negative” class of bacteria is an essential organelle and a robust permeability barrier that prevents many antibiotics from reaching their intracellular targets (1). The OM is a unique asymmetrical lipid bilayer (Fig.

Biochemical analysis of TssK, a core component of the bacterial Type VI secretion system, reveals distinct oligomeric states of TssK and identifies a TssK–TssFG subcomplex [PDF]
, 2014 Gram-negative bacteria use the Type VI secretion system (T6SS) to inject toxic proteins into rival bacteria or eukaryotic cells. However, the mechanism of the T6SS is incompletely understood. In the present study, we investigated a conserved component of

Role of Outer Membrane Vesicles in Bacterial Physiology and Host Cell Interactions
Infectious Microbes & Diseases, 2020 . Outer membrane vesicles (OMVs) are spherical particles shed from the outer membrane of Gram-negative bacteria, which contain the typical components present in the outer membrane, although enrichment of specific molecules may occur, and furthermore a ...
