Detection of the babA2 adhesin gene in Helicobacter pylori clinical isolates and correlation with upper gastrointestinal diseases [PDF]

open access: yesAnais da Academia Brasileira de Ciências
Helicobacter pylori is an oncobacteria that infects more than half of the world’s population. Adhesins are virulence factors that are essential for the microorganism to bind to the gastric mucosa, such as the BabA adhesion protein, which is associated ...

Super-Resolution Imaging of Protein Secretion Systems and the Cell Surface of Gram-Negative Bacteria

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Gram-negative bacteria have a highly evolved cell wall with two membranes composed of complex arrays of integral and peripheral proteins, as well as phospholipids and glycolipids.

Outer membrane biogenesis in Helicobacter pylori: A deviation from the paradigm

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
The bacterial pathogen Helicobacter pylori is capable of colonizing the gastric mucosa of the human stomach using a variety of factors associated with or secreted from its outer membrane (OM).

Bacterial Outer Membranes and Interactions with Membrane Proteins [PDF]

open access: yesBiophysical Journal, 2015
Because the bacteria's outer membrane (OM) acts as an effective barrier against the permeation of both hydrophobic and hydrophilic compounds, gram-negative cell permeation is one of the biggest challenges to the discovery of novel antibiotics for bacterial infections and antibiotic resistance worldwide.

Comprehensive in silico prediction and analysis of chlamydial outer membrane proteins reflects evolution and life style of the Chlamydiae

open access: yesBMC Genomics, 2009
Background Chlamydiae are obligate intracellular bacteria comprising some of the most important bacterial pathogens of animals and humans. Although chlamydial outer membrane proteins play a key role for attachment to and entry into host cells, only few ...

Stress-Responsive Periplasmic Chaperones in Bacteria

open access: yesFrontiers in Molecular Biosciences, 2021
Periplasmic proteins are involved in a wide range of bacterial functions, including motility, biofilm formation, sensing environmental cues, and small-molecule transport. In addition, a wide range of outer membrane proteins and proteins that are secreted

β-Barrel Assembly Machinery (BAM) Complex as Novel Antibacterial Drug Target

open access: yesMolecules, 2023
The outer membrane of Gram-negative bacteria is closely related to the pathogenicity and drug resistance of bacteria. Outer membrane proteins (OMPs) are a class of proteins with important biological functions on the outer membrane.

Preparation of Bacterial Outer Membrane Vesicles for Characterisation of Periplasmic Proteins in Their Native Environment

open access: yesBio-Protocol, 2020
Bacterial outer membrane vesicles (OMVs) are naturally formed by budding from the outer membrane of Gram-negative bacteria. OMVs consist of a lipid bilayer identical in composition to the original outer membrane and contain periplasmic content within ...

Dissecting Escherichia coli outer membrane biogenesis using differential proteomics. [PDF]

open access: yesPLoS ONE, 2014
The cell envelope of Gram-negative bacteria is a complex multi-layered structure comprising an inner cytoplasmic membrane and an additional asymmetric lipid bilayer, the outer membrane, which functions as a selective permeability barrier and is essential

Effect of Energy Metabolism on Protein Motility in the Bacterial Outer Membrane [PDF]

open access: yesBiophysical Journal, 2009
We demonstrate the energy dependence of the motion of a porin, the lambda-receptor, in the outer membrane of living Escherichia coli by single molecule investigations. By poisoning the bacteria with arsenate and azide, the bacterial energy metabolism was stopped.
