The BaeSR two-component system activates bamK, a paralog of the essential β-barrel foldase bamA, in Klebsiella pneumoniae

mBio
β-Barrel outer membrane proteins (OMPs) perform critical functions in gram-negative bacteria including outer membrane biogenesis, nutrient acquisition, and efflux.

A New Strain Collection for Improved Expression of Outer Membrane Proteins

Frontiers in Cellular and Infection Microbiology, 2017
Almost all integral membrane proteins found in the outer membranes of Gram-negative bacteria belong to the transmembrane β-barrel family. These proteins are not only important for nutrient uptake and homeostasis, but are also involved in such processes ...

Deoxyribonucleic acid and outer membrane: binding to outer membrane involves a specific protein [PDF]

Journal of Bacteriology, 1979
The binding of deoxyribonucleic acid (DNA) to the outer membrane of Escherichia coli was examined. The amount of DNA found to be bound to outer membrane was low and was estimated to be about 0.4% of the total DNA. Treatment of cells with chloramphenicol or rifampin caused a disassociation of the apparent DNA-outer membrane complex.

Dynamic architecture of mycobacterial outer membranes revealed by all-atom simulations

eLife
Tuberculosis remains a global health crisis due to the resilience of Mycobacterium tuberculosis (Mtb), largely attributed to its unique cell envelope. The impermeability and structural complexity of the outer membrane of this envelope, driven by mycolic ...

Isolation of Chloroplast Inner and Outer Envelope Membranes

Bio-Protocol, 2015
The chloroplast is an important organelle found in plant cells that conduct photosynthesis. It is enclosed by a pair of closely spaced membranes, the double-membrane envelope, consisting of the inner membrane bounding the matrix or stroma and the outer ...

Outer membrane vesicles and the outer membrane protein OmpU govern Vibrio cholerae biofilm matrix assembly

mBio
Biofilms are matrix-encased microbial communities that increase the environmental fitness and infectivity of many human pathogens including Vibrio cholerae. Biofilm matrix assembly is essential for biofilm formation and function.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

High yield production process for Shigella outer membrane particles. [PDF]

PLoS ONE, 2012
Gram-negative bacteria naturally shed particles that consist of outer membrane lipids, outer membrane proteins, and soluble periplasmic components. These particles have been proposed for use as vaccines but the yield has been problematic.

A network of cytosolic (co)chaperones promotes the biogenesis of mitochondrial signal-anchored outer membrane proteins

eLife, 2022
Signal-anchored (SA) proteins are anchored into the mitochondrial outer membrane (OM) via a single transmembrane segment at their N-terminus while the bulk of the proteins is facing the cytosol.
