There is a strand-based evolutionary mechanism for the diversification of outer membrane proteins, which has implications for how repeat proteins are created and for how outer membrane proteins fold.

Dispensable loops shield the functionally-important extracellular loops of the essential Gram-negative bacterial outer membrane protein LptD from antibody interference.

Temperature-sensitive mitochondrial outer membrane proteins used as novel quality control substrates reveal a unique mitochondria-associated degradation pathway consisting of both cytosolic and mitochondrial ubiquitin-proteasome system machinery.

Physical contact between two Myxococcus xanthus cells is sufficient to fuse their outer membrane transiently and exchange outer membrane proteins and lipids at high efficiency.

Auxiliary proteins play functional roles in modulating the assembly and activity of a non-canonical ABC transporter that is important for the maintenance of outer membrane lipid asymmetry.

The range of barrel-shaped proteins found in the outer membrane of certain bacteria evolved through multiple pathways.

Outer membrane β-barrel proteins in Gram-negative bacteria are assembled within the lumen of the BamA β-barrel.

Input from computational models has enabled the detection of allosteric communication that modulates the gating mechanism of a bacterial outer-membrane protein.

The C-terminal membrane binding domain of Bim is shown to interact with and activate Bim enabling it to kill cells not dependent on anti-apoptotic proteins for survival.
