Mechanisms of Protein Export across the Bacterial Outer Membrane [PDF]
Gram-negative bacteria secrete a wide range of proteins whose functions include biogenesis of organelles, such as pili and flagella; nutrient acquisition; virulence; and efflux of drugs and other toxins. Export of these proteins to the bacterial surface involves transport across the inner membrane (IM), periplasm, and outer membrane (OM) of the cell ...

HELICOBACTER PYLORI OIPA VIRULENCE GENE AS A MOLECULAR MARKER OF SEVERE GASTROPATHIES [PDF]
Background: Helicobacter pylori is an etiologic agent of gastroduodenal diseases. The microorganism, considered a type I carcinogen, affects about 50% of the global population. H.

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

Interactions between folding factors and bacterial outer membrane proteins [PDF]
SummaryThe outer membrane is the first line of contact between Gram‐negative bacteria and their external environment. Embedded in the outer membrane are integral outer membrane proteins (OMPs) that perform a diverse range of tasks. OMPs are synthesized in the cytoplasm and are translocated across the inner membrane and probably diffuse through the ...

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

Stress-Responsive Periplasmic Chaperones in Bacteria
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
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.

Bacterial Outer Membranes and Interactions with Membrane Proteins [PDF]
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.
