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).

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]

open access: yes, 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

Membrane proteins and proteomics: Love is possible, but so difficult [PDF]

open access: yes, 2009
Despite decades of extensive research, the large-scale analysis of membrane proteins remains a difficult task. This is due to the fact that membrane proteins require a carefully balanced hydrophilic and lipophilic environment, which optimum varies with ...

Nanopods: A New Bacterial Structure and Mechanism for Deployment of Outer Membrane Vesicles [PDF]

open access: yes, 2011
Background: Bacterial outer membrane vesicles (OMV) are packets of periplasmic material that, via the proteins and other molecules they contain, project metabolic function into the environment.

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.

Protein sorting to mitochondria [PDF]

open access: yes, 1990
According to the endosymbiont hypothesis, mitochondria have lost the autonomy of their prokaryotic ancestors. They have to import most of their proteins from the cytosol because the mitochondrial genome codes for only a small percentage of the ...
