Evolutionary pathways of repeat protein topology in bacterial outer membrane proteins [PDF]

eLife, 2018
Outer membrane proteins (OMPs) are the proteins in the surface of Gram-negative bacteria. These proteins have diverse functions but a single topology: the β-barrel.

Solution nuclear magnetic resonance spectroscopy of bacterial outer membrane proteins in natively excreted vesicles using engineered Escherichia coli [PDF]

MicrobiologyOpen, 2022
Gaining structural information on membrane proteins in their native lipid environment is a long‐standing challenge in molecular biology. Instead, it is common to employ membrane mimetics, which has been shown to affect protein structure, dynamics, and ...

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.

Dual recognition of multiple signals in bacterial outer membrane proteins enhances assembly and maintains membrane integrity [PDF]

eLife
Outer membrane proteins (OMPs) are essential components of the outer membrane of Gram-negative bacteria. In terms of protein targeting and assembly, the current dogma holds that a ‘β-signal’ imprinted in the final β-strand of the OMP engages the β-barrel

Bacterial outer membrane proteins assemble via asymmetric interactions with the BamA β-barrel [PDF]

Nature Communications, 2019
The integration of β-barrel proteins into the bacterial outer membrane (OM) is catalysed by the β-barrel assembly machinery (BAM). Here authors develop a method to trap an E.

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 Ton Motor

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.
