Emerging Roles for NlpE as a Sensor for Lipoprotein Maturation and Transport to the Outer Membrane in Escherichia coli

open access: yesmBio, 2019
Outer membrane biogenesis is a complex process for Gram-negative bacteria as the components are synthesized in the cytoplasm or at the inner membrane and then transported to the outer membrane.

Structural characterisation of outer membrane proteins from Borrelia burgdorferi sensu lato by small-angle X-ray scattering [PDF]

open access: yes, 2016
Forming the interface between the bacterial cell and the host, the outer membrane of Borrelia is known to play a key role in pathogenicity. Although Borrelia burgdorferi sensu lato are considered to be Gram-negative, their outer membrane is unique ...

Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]

open access: yes, 1992
Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

Analysis of Moraxella catarrhalis Outer Membrane Protein Profiles

open access: yesBio-Protocol, 2013
Phenotypes observed for certain Moraxella catarrhalis wild-type strains or mutants may be caused by a variety of factors including alteration of outer membrane protein composition. Examination of the outer membrane protein profiles may be a valuable tool

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

open access: yesmBio
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

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 ...

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.

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

open access: yeseLife
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

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 ...

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.
