Not All Bacterial Outer-Membrane Proteins Are β-Barrels. [PDF]
The discovery of Wza, an octomeric helical barrel integral bacterial outer-transmembrane protein, has challenged the widely held understanding that all integral outer-membrane proteins of Gram-negative bacteria are closed β-barrels composed of transmembrane β- strands.

Protein-protein interactions and the spatiotemporal dynamics of bacterial outer membrane proteins.
It has until recently been unclear whether outer membrane proteins (OMPs) of Gram-negative bacteria are organized or distributed randomly. Studies now suggest promiscuous protein-protein interactions (PPIs) between β-barrel OMPs in Escherichia coli govern their local and global dynamics, engender spatiotemporal patterning of the outer membrane into ...

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 ...

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 ...

Solute channels of the outer membrane: from bacteria to chloroplasts [PDF]
Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding
