Outer-membrane vesicles from Gram-negative bacteria: biogenesis and functions

open access: yesNature Reviews Microbiology, 2015
Outer-membrane vesicles (OMVs) are spherical buds of the outer membrane filled with periplasmic content and are commonly produced by Gram-negative bacteria.

Distinct Roles of Outer Membrane Porins in Antibiotic Resistance and Membrane Integrity in Escherichia coli

open access: yesFrontiers in Microbiology, 2019
A defining characteristic of Gram-negative bacteria is the presence of an outer membrane, which functions as an additional barrier inhibiting the penetration of toxic chemicals, such as antibiotics.

Analysis of Moraxella catarrhalis Outer Membrane Protein Profiles

open access: yesBio-Protocol, 2013
Phenotypes observed for certain Moraxella catarrhalis wild-type strains or mutants may be caused by a variety of factors including alteration of outer membrane protein composition. Examination of the outer membrane protein profiles may be a valuable tool

Outer Membrane Vesicles (OMVs) of Gram-negative Bacteria: A Perspective Update

open access: yesFrontiers in Microbiology, 2017
Outer Membrane Vesicles (OMVs) of Gram-negative bacteria are spherical membrane-enclosed entities of endocytic origin. Reported in the consortia of different bacterial species, production of OMVs into extracellular milieu seems essential for their ...

Deoxyribonucleic acid and outer membrane: binding to outer membrane involves a specific protein [PDF]

open access: yesJournal of Bacteriology, 1979
The binding of deoxyribonucleic acid (DNA) to the outer membrane of Escherichia coli was examined. The amount of DNA found to be bound to outer membrane was low and was estimated to be about 0.4% of the total DNA. Treatment of cells with chloramphenicol or rifampin caused a disassociation of the apparent DNA-outer membrane complex.

Prediction of β-barrel membrane proteins by searching for restricted domains [PDF]

open access: yes, 2005
BACKGROUND: The identification of beta-barrel membrane proteins out of a genomic/proteomic background is one of the rapidly developing fields in bioinformatics. Our main goal is the prediction of such proteins in genome/proteome wide analyses.

Bacterial outer membrane vesicles suppress tumor by interferon-γ-mediated antitumor response

open access: yesNature Communications, 2017
Gram-negative bacteria actively secrete outer membrane vesicles, spherical nano-meter-sized proteolipids enriched with outer membrane proteins, to the surroundings.

Single-channel measurements of an N-acetylneuraminic acid-inducible outer membrane channel in Escherichia coli [PDF]

open access: yes, 2012
NanC is an Escherichia coli outer membrane protein involved in sialic acid (Neu5Ac, i.e., N-acetylneuraminic acid) uptake. Expression of the NanC gene is induced and controlled by Neu5Ac. The transport mechanism of Neu5Ac is not known.

The BaeSR two-component system activates bamK, a paralog of the essential β-barrel foldase bamA, in Klebsiella pneumoniae

open access: yesmBio
β-Barrel outer membrane proteins (OMPs) perform critical functions in gram-negative bacteria including outer membrane biogenesis, nutrient acquisition, and efflux.

A New Strain Collection for Improved Expression of Outer Membrane Proteins

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Almost all integral membrane proteins found in the outer membranes of Gram-negative bacteria belong to the transmembrane β-barrel family. These proteins are not only important for nutrient uptake and homeostasis, but are also involved in such processes ...
