Extraction and Electrophoretic Analysis of Bacterial Lipopolysaccharides and Outer Membrane Proteins
Bio-Protocol, 2021 Lipopolysaccharides (LPS) (or lipooligosaccharides [LOS], which lack the O-antigen side chains characteristic of LPS), and outer membrane proteins (OMP) are major cell-surface molecules in the outer membrane (OM) of gram-negative bacteria.

Inflammasome Activation by Bacterial Outer Membrane Vesicles Requires Guanylate Binding Proteins
mBio, 2017 The Gram-negative bacterial cell wall component lipopolysaccharide (LPS) is recognized by the noncanonical inflammasome protein caspase-11 in the cytosol of infected host cells and thereby prompts an inflammatory immune response linked to sepsis.

Protein oligomerization in the bacterial outer membrane (Review) [PDF]
Molecular Membrane Biology, 2009 The formation of homo-oligomeric assemblies is a well-established characteristic of many soluble proteins and enzymes. Oligomerization has been shown to increase protein stability, allow allosteric cooperativity, shape reaction compartments and provide multivalent interaction sites in soluble proteins. In comparison, our understanding of the prevalence

Protein import and export across the bacterial outer membrane
Current Opinion in Structural Biology, 2021 The bacterial outer membrane forms an impermeable barrier to the environment, but a wide variety of substances must cross it without compromising the membrane. Perhaps, the most fascinating transport phenomenon is the import and export of very large protein toxins using relatively small β-barrel proteins residing in the outer membrane.

Entry and exit of bacterial outer membrane proteins. [PDF]
Trends Microbiol, 2015 The sites of new outer membrane protein (OMP) deposition and the fate of pre-existing OMPs are still enigmatic despite numerous concerted efforts. Rassam et al. identified mid-cell regions as the primary entry points for new OMP insertion in clusters, driving the pre-existing OMP clusters towards cell poles for long-term storage.

The simulation approach to bacterial outer membrane proteins (Review) [PDF]
Molecular Membrane Biology, 2004 The outer membrane of Gram-negative bacteria serves as a protective barrier against the external environment but is rendered selectively permeable to nutrients and waste by proteins called porins. Other outer membrane proteins (OMPs) provide the membrane with a variety of other functions including active transport, catalysis, pathogenesis and signal ...

Frontiers in Microbiology, 2022 The Ton complex is a molecular motor at the inner membrane of Gram-negative bacteria that uses a proton gradient to apply forces on outer membrane (OM) proteins to permit active transport of nutrients into the periplasmic space.

Subdominant antigens in bacterial vaccines: AM779 is subdominant in the Anaplasma marginale outer membrane vaccine but does not associate with protective immunity. [PDF]
PLoS ONE, 2012 Identification of specific antigens responsible for the ability of complex immunogens to induce protection is a major goal in development of bacterial vaccines.
