Bacterial outer membrane constriction [PDF]

open access: yesMolecular Microbiology, 2018
SummaryThe outer membrane of Gram‐negative bacteria is a crucial permeability barrier allowing the cells to survive a myriad of toxic compounds, including many antibiotics. This innate form of antibiotic resistance is compounded by the evolution of more active mechanisms of resistance such as efflux pumps, reducing the already limited number of ...

Solute channels of the outer membrane: from bacteria to chloroplasts [PDF]

open access: yes, 2007
Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding

A New Strain Collection for Improved Expression of Outer Membrane Proteins

open access: yesFrontiers 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 ...

Mitofusins and OPA1 Mediate Sequential Steps in Mitochondrial Membrane Fusion [PDF]

open access: yes, 2009
Mitochondrial fusion requires the coordinated fusion of the outer and inner membranes. Three large GTPases—OPA1 and the mitofusins Mfn1 and Mfn2—are essential for the fusion of mammalian mitochondria.

Isolation of Chloroplast Inner and Outer Envelope Membranes

open access: yesBio-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 ...

Insights into the structure of Escherichia coli outer membrane as the target for engineering microbial cell factories

open access: yesMicrobial Cell Factories, 2021
Escherichia coli is generally used as model bacteria to define microbial cell factories for many products and to investigate regulation mechanisms. E.

Engineering Planar Gram-Negative Outer Membrane Mimics Using Bacterial Outer Membrane Vesicles

open access: yesLangmuir, 2023
AbstractAntibiotic resistance is a major challenge in modern medicine. The unique double membrane structure of gram-negative bacteria limits the efficacy of many existing antibiotics and adds complexity to antibiotic development by limiting transport of antibiotics to the bacterial cytosol. New methods to mimic this barrier would enable high-throughput

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

open access: yeseLife, 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.

A Receptor Component of the Chloroplast Protein Translocation Machinery [PDF]

open access: yes, 1994
The chloroplast outer envelope protein OEP86 functions as a receptor in precursor protein translocation into chloroplasts. Sequence analysis suggests that the precursor of OEP86 is directed to the chloroplast outer envelope by a cleavable, negatively ...

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

open access: yesmBio
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.
