Peptidoglycan Remodeling Enables Escherichia coli To Survive Severe Outer Membrane Assembly Defect

mBio, 2019
In Gram-negative bacteria, the outer membrane protects the cell against many toxic molecules, and the peptidoglycan layer provides protection against osmotic challenges, allowing bacterial cells to survive in changing environments.

Outer Membrane Vesicle—Host Cell Interactions

Microbiology spectrum, 2019
Outer membrane vesicles (OMVs) are nanosized proteoliposomes derived from the outer membrane of Gram-negative bacteria. They are ubiquitously produced both in culture and during infection and are now recognized to play crucial roles during host-microbe ...

Charge Asymmetry in the Proteins of the Outer Membrane [PDF]

Biophysical Journal, 2013
Abstract Motivation: Outer membrane beta-barrels (OMBBs) are the proteins found in the outer membrane of bacteria, mitochondria and chloroplasts. There are thousands of beta-barrels reported in genomic databases with ∼2–3% of the genes in gram-negative bacteria encoding these proteins.

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 ...

Characterization of the protein import apparatus in isolated outer envelopes of chloroplasts [PDF]

, 1991
Isolated outer envelope membrane from pea (Pisum sativum L.) chloroplasts can be used in vitro to study binding and partial translocation of precursor proteins destined for the inside of the organelle.

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 ...

Cross-species chimeras reveal BamA POTRA and β-barrel domains must be fine-tuned for efficient OMP insertion [PDF]

, 2015
BAM is a conserved molecular machine, the central component of which is BamA. Orthologues of BamA are found in all Gram-negative bacteria, chloroplasts and mitochondria where it is required for the folding and insertion of β-barrel containing integral ...
